association chained accessors

Hello

Please see the article by Steve

[http://www.oracle.com/technology/oramag/oracle/05-nov/o65frame.html]
public boolean validateDiscountAmount() {
  return getDiscount().getValue() <= 0.05 || 
  getOrder().getCustomer().getStatus().equals("Gold");
}
He calls who has chained accessors of the association: first to getOrder(), then to getCustomer().
then getStatus() to get the status of this customer.




My question is from a procedural background
How will I know that there is a method named getOrder
and also by placing a point after getOrder I can make a call to getCustomer

Hello

in Java, you work primarily with objects. Objects have State and behavior, exposed through methods. This code is executed in the class has a getOrder method, which returns an instance of the OrderImpl class. This is therefore a getCustomer method to return an instance of CustomerImpl. Implementation classes have typed accessors for attributes, like getStatus() in the example. You know this string of methods by the presentation of the model of the ADF BC. JDeveloper also, lets figure you this out by exposing the methods of a class in the Structure window and providing an overview of code after you set the '. ' dot

  • Accessors classic vs. chained setters

    I am designing an API. My first thought is to use the getters and setters classic, JavaBeans-like.
    But there are some classes in the Java API which adopt a different approach. ProcessBuilder comes to my mind.
    Look at this:
    File directory() 
              Returns this process builder's working directory. 
    ProcessBuilder directory(File directory) 
              Sets this process builder's working directory. 
    
    boolean redirectErrorStream() 
              Tells whether this process builder merges standard error and standard output. 
    ProcessBuilder redirectErrorStream(boolean redirectErrorStream) 
              Sets this process builder's redirectErrorStream property. 
    What are essentially setters and getters with a twist: the set accessors of return the object on which they are called, and the naming convention is different.
    The only advantage I see for this approach is that we can write code such as:
    ProcessBuilder pb = new ProcessBuilder(...).redirectErrorStream(true).directory(...);
    What is syntactic sugar, I think.
    We can also write code such as:
    pb.redirectErrorStream(); // It does not do what the name implies, it does nothing!
    The last error is the result of the loss of the absolute certainty that the old naming convention provided: accessors get and Set together.
    Not to mention that it smells like an abuse of overload.
    I see a compromise: use the old naming convention, but return the object of bombers.
    What I don't like in this topic, it is that I'm being "smart" and how others don't think about it. Maybe they had good reason.

    My question: is the motive ProcessBuilder approach any? Where can I read about it, when to use and when not?
    Any thoughts appreciated.

    Published by: baftos on March 12, 2011 10:25

    Although I find this elegant style in general, I agree with you that the naming porr and 'misuse of overload' in the use of ProcessBuilder are clumsy and prone to error.

    What is syntactic sugar, I think.

    Perhaps. What I like about this style, is that it allows to write code that reads more in plain English (EDIT of Fowler more reasonably mean Domain-Specific Language - a subject of his pet).

    See for example the Joda-time API (quoting from memory, but bear with me):

    /**
     * Ship the following tuesday, 1 hour later than the order's time
     */
    public Date computeDeliveryDate(Date orderDate) {
        return new DateTime(orderDate).plusWeek(1).withDay(TUESDAY).toDate();
    }
    

    I realize, that Joda-time, while encouraging a matter of method chaining , is not strictly a FluentInterface : chained indeed methods will work on different instances ( DateTime instances are immutable, and the methods of "mutator" indeed return a different instance each time (so not what you call in your OP).

    When to use and when not?

    After this last remark, a beneficial side effect might be that the client code could be unchanged if at a given time, transform you your mutable object in an immutable. But I wouldn't count on it, because it's impossible to guarantee and no doubt difficult to check, if all client code constantly mobilized the style 'fluent '.

  • Windows 7: chain explorer.exe endlessly about the file type association

    Today I tried to .jar archives open as files compressed by default instead of running in Java on opening. My first guess on how to proceed was with C:/Windows/explorer.exe, and I did it by r-click on a .jar file, select open with > choose default program... then by navigating to the explorer.exe directory and check the "always use the selected program to open this type of file."

    This is where it goes horribly wrong. Apparently, Windows Explorer cannot say himself to open a file with itself. When I try to open a .jar file that is set to open with Windows Explorer, an endless loop of explorer.exe (in thousands) process starts one after the other, until I have run out of memory. To get rid of them, I have to restart.
    Subsequently, the checkbox "Always use the selected program to open this kind of file" is grayed out, so I can't restore the association to its original. Using the command "assoc = CompressedFile .jar ' is as useless."
    How to restore the original file .jar extension association? Also, to solve my original problem, how can I make Windows opens files .jar and folders compressed instead of using Java.exe?

    I know that the default handler for ZIP is not an executable file directly, but it should be possible to associate with other types.  Filetype associations have two parts: a type of file that describes the file, like "file of Adobe Reader.  Then, who is paired with the type manager who actually links to the actions associated with the opening of this kind.

    For jar files to open with the same manager as ZIP, only one side of this pair should be changed in the registry, the .jar extension.  But I wouldn't really recommend a do it manually because of the potential problems of editing the registry.  Set a restore point or backup of the registry, then try the following steps - at your own risk/peril :)
    • Look at HKEY_CLASSES_ROOT\.zip and see the structure.  Note that it says .zip is CompressedFolder.
    • Knowing this, look at HKEY_CLASSES_ROOT\CompressedFolder.  Here you can see the actual command used to open these files (as well as the "friendly display name' which is used to describe these files when you hover over them and others).
    • For JAR files to do the same, you just change the .jar entry, then set it to the default CompressedFolder type.  Who told him to use the same settings as CompressedFolder.
  • Is there a better method chained and associated problem?

    I used chained for awhile now.  I searched and reviewed the cross fader help on the forum without finding far more than information or a solution.

    My method:

    -Razor point be dissolved

    -Drag the chained until the razor

    -Click on the dissolution to select the required length

    -Razor each end of the length of dissolve

    -Right-click on each section razored with a ripple delete

    -Reapply the cross fader and reselect the length

    I find it works for me, but could be more simple.  I ripple delete sections razored because if I don't, the cross dissolves overlaps previous front sections and after the clips selected in the entirety of the video sequence such that the effect seems not work.  Ripple deleting ensures that the previous sections are in the selected clips.  There must be a quicker way.

    My problem:

    This happens after several successful cross dissolves into a project I ran off qualifying times, it can be used.  When I try to ripple delete sections razored, ripple deleting does not have little matter what I do.

    What I can do better or properly to cross dissolve them and how I take care of deletions ripple premature failure?

  • opening running associated extension exe

    My built LabVIEW application is associated with a specific file type in Windows:

    http://social.msdn.Microsoft.com/forums/vstudio/en-us/630ed1d9-73f1-4cc0-BC84-04f29cffc13b/what-REGI...

    and opens double click on the file using the command line argument:

    http://forums.NI.com/T5/LabVIEW/passing-files-into-LabVIEW-VI-by-opening-the-file/m-p/138968/HIGHLIG...

    This allows me to _launch_ my request, when the user double-clicks a file with the specified extension and process this file.

    But it happens only if the application is not running.

    What should I do if I want to open the double clicked when my program works?

    Any system event happening that I can record and process?

    The only way I see now is to build an intermediate application that will be associated with extension, check if the main application is running and pass arguments to it.

    Alexander_Sobolev

    Well, there were many discussions on this subject, for example 1, 2, 3 , and in the early days, I tried a few ways of implementation of DDE in my applications. You may use the private property of LabVIEW which is called "OS Open Document" (needs SuperSecretPrivateSpecialStuff = true Labview.ini chain so that it is visible in the window configuration of events). More information is presented here and hereand it worked for me... I also find more elegantly and found this article. LabVIEW has already integrated server DDE and your application can receive WM_DDE_EXECUTE message using calls to the system API. So, I made an example of this receiver - it works if you have saved a file extension in Windows (HKEY_CLASSES_ROOT branch in the registry) and is a double click of your file. This also works when you double-click a shortcut to your application and when you double-click your application exe, even if it is already running. It does not work if you have saved your file with key ddeexec extension (equivalent to open (%)) with command key 1 (equals "Path to your app\App.exe" '%1').)) But in this case, the "OS Open Document" private property works! And you can even use both methods or can choose one of them.

    For the look of simplicity these registry keys. If you have saved *.ton file extension, you should have

    [HKEY_CLASSES_ROOT\.ton]
    @="ton_auto_file"
    

    and

    [HKEY_CLASSES_ROOT\ton_auto_file\shell\open\command]
    @="\"C:\\Test\\Application.exe\" \"%1\""
    

    the registry keys. In this case the method 1 will work. If you add this key

    [HKEY_CLASSES_ROOT\ton_auto_file\shell\open\ddeexec]
    @="open(%1)"
    

    then the method 1 does not work, but the method 2 ("OS Open Document") will work.

    My test program is in attachment (LV 2011). It requires Windows Message Queue library (second link is for LV 2009 and greater) for the interception of DDE messages. You can integrate the message listener loop in parallel thread in your application and stop with the notifier or a similar mechanism.

  • MCBUILDER. EXE running rampant, competing with updates for CPU and possibly associated with an update failed chess SP2 and the backup and restore

    Running Vista Home Premium SP1 and the system has been slow and freezing. MCbuilder appear to be using 50 to 100% of CPU, and it is a process that seems no way of killing. I disabled in Services, but again, it seems to start without any particular reason and hinders attempts to install programs or updates vista hogging resources. This can be associated with a problem that has arisen since June because I am not able to perform backups or set restore points (gives the error "0 x 81000101 the creation of a shadow copy has timed out"). I tried to install SP2 in the hope that it will not solve the problem, but the failure of installation and install KB947821 doesn't seem to work either. As the restoration of the system is defective, I would be grateful for the pointers to the resolve or completely remove this mcbuilder problem.

    You have COMODO or AVG Antii-virus installed on your system?  It is known problems with these two programs and MCbuilder.exe.  I don't have Microsoft Resource Builder Cache as a service in the Services (so I can't activate or deactivate it)-you which version of Vista to help (bit, SP-number version)?  I have 32 bit Vista Business SP2. I see no way to turn it off in order to close it with the Task Manager when it is - with the exception, but who could become annoying if it happens frequently and with multiple instances.  I could find nothing useful in Knowledge Base Microsoft on it hogging resources although I've seen a few threads using Bing (which is where I came up with COMODO and AVG anti-virus conflicts).

    You can be infected by malware (which may be the origin of the program to activate and run "without reason"). While in Test Mode safe mode (press F8 during startup and select mode safe mode with networking repeatedly) to run anti-malware programs. To resolve this problem (if it is a problem) download, install, and run the following two programs: http://www.malwarebytes.org/mbam.php and http://www.safer-networking.org/en/index.html.  You can also try a free trial of Pandasoft (www.pandasoft.com).  Before you download pandasoft, uninstall all anti-virus program you currently use (because the installation and execution of two simultaneously can cause conflicts, freezes and all sorts of problems).  Once you have uninstalled your current AV program, download, install, update and scan using Pandasoft.  I think you might be amazed at how much she notes that other software missed.  Once complete, uninstall pandasoft and re - install your current AV program (unless you decide to spend that I did when I tried about 4 years ago).  You can also try the new, free Microsoft Security Essentials http://www.microsoft.com/security_essentials/default.aspx (with the same caveat that only program AV one ALONE can be installed and running on your system at any time). Restart after finishing all the scans and see if the problem has been resolved.

    Try a system restore to a point in time BEFORE the problem started (which can be a problem if it began all the way back in June - you should have posted here then when this process would probably have worked).  Here is the procedure: http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/.  Don't forget to check the box to show more than 5 days of restore points (but I doubt that you will have a pretty far back and forth to the system restore may not be a viable option).  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re - install any software and updates that you have installed between now and the restore point, but you can use Windows Update for updates.

    If the system restore does not work, do a startup repair, boot from the disk Installation of Windows Vista genuine (or one that you can borrow from someone) or a recovery disc.  Here is the procedure: http://www.bleepingcomputer.com/tutorials/tutorial148.html.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.

    If you do not have a floppy disk, you can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD.

    If this does not work, try to start in safe mode (repeatedly hit F8 key so that the start and go in safe mode with networking).  Then we will check some of your system files:

    Go to start / all programs / accessories / command prompt and right click on command prompt, and then click Run as administrator.

    Type sfc/scannow, go and let it run.  It will scan and try to correct some of your system files.  If all goes well it will complete with no corruption, he couldn't fix it (if there is such corrouption post here or try to analyze it to find the problem or files using http://support.microsoft.com/kb/928228.  I bet there is something involving the program or associated with this program.

    If this does not work, you will need to do a repair/system upgrade using the Windows Vista Installation disc authentic (you own or that you can borrow from someone).  Here is the procedure: http://www.vistax64.com/tutorials/88236-repair-install-vista.html as well as the upgrade from an earlier version of the Windows section of the following: http://support.microsoft.com/kb/918884.  Although this will not affect your data, settings or programs, you should always back up your data before you start just be on the safe side.

    I hope one of these procedures can solve your problem (probably the SFC command or controls anti-virus).  If this isn't the case, after return and we will try something else.  Return message anyway so we know how it turns out.

    BTW, for update of the problems you are having with SP2, post on the Forum of Windows Update to: http://social.answers.microsoft.com/Forums/en-US/vistawu/threads where the people who specialize in update issues will be happy to help you with your concerns and get SP2 running on your system (perhaps despite this particular problem).  As you say, it can even solve the problem - who knows.

    Good luck!

    How do I... Change file extension associations in Windows Vista?

  • If I click on anything whatsoever on my desk, a window appears: this file does not have a program associated with it for performing this action. Create an association in the control panel to define the Associations. "

    Original title: all my programs have become more associated with their shortcuts in my windows start.

    All my programs became most associated with their shortcuts. If I click on anything whatsoever on my desk, a window appears: "this file has no program associated with it for performing this action. Create an association in the control panel to define the Associations. " I must do this for each shortcut? Microsoft Word, all my accessories, none of the links are attached to nothing. Y at - it a quick fix to my problem, or I am looking at a restore of the entire system?  Help, please!

    Look at the tutorial on changing to default file associations.

  • Cannot open certain e-mail messages. He askes me to define an association in the Control Panel, but do not know how to configure...

    Remember - this is a public forum so never publish information such as email or phone numbes:

    • You have problems with programs
    • Error messages
    • Recent changes to your computer
    • What you have already tried to solve the problem

    Please, in the future, remove all the verbiage above when you ask for a
    issue. It has nothing to do with your question. And ask your
    questions in the body of the message, not in the title. The title
    should be used only for a brief description of what is the question
    everything.

    You say 'impossible to open certain emails', but makes the rest of your title
    It sounds like you can open the e-mail message, but you cannot open
    the accessories that come with them. Is this correct?

    If that's right, read the following:

    To open a file (if get you it as an attachment or any other)
    by the way), you must have an appropriate program installed for him (be it
    the program that created the file or a compatible program). So if you open attachments depends on what kind of files (the
    extension, the characters after the dot at the end of the file name)
    attachments are.

    If you get the files .doc or .docx, these were created by Microsoft Word
    (or a compatible program) and to open them, you need Word, or
    compatible program. Microsoft Office Home and Student includes Word.
    You can also use OpenOffice (free software that is largely compatible
    with Microsoft Office), WordPerfect, etc. Or you can download and
    Install the free Microsoft Word Viewer
    http://www.Microsoft.com/downloads/details.aspx?FamilyId=3657ce88-7cfa-457a-9aec-f4f827f20cac&displaylang=en
    or http://tinyurl.com/2w3s6z the viewer will allow you to read existing
    files, but not create or modify them.

    To open .pdf files, you need a viewer pdf and Microsoft Office Home
    and student will not help you. The standard pdf viewer than most people
    the use is Adobe Reader, and you can download free of charge
    http://get.Adobe.com/reader/

    It is more likely that you don't have a proper file installed
    that you don't have the correct association, but if a
    an appropriate program is installed, just right click on any file .doc
    and choose open with. Highlight and select Word, select the check box
    "Always use this program...". "and click OK. It should work fine
    from then on it.
    The above paragraph is how do to the files .doc and Word, but for
    other types of files, replace .doc with the extension of the file type and
    Word with the appropriate program.
    If you try in vain to open other types of attachments,
    Please tell us what types of files they are.

  • the control panel fixed association, he say of cereate Association for this

    PPS. I can not open emails with attached pps more. He said, to create an association in THE SET ASSOCIATION CONTROL PANEL

    I assume you have the http://support.microsoft.com/kb/126492 PowerPoint or PowerPoint or OpenOffice Suite www.openoffice.crg Viewer or another program to view and/or to open PPS files installed on your system.  If this isn't the case, you must do so before you will be able to view attachments of type pps (use the links above to get the software if necessary).

    To check the file Association, click on start / "default programs / Associate a file or Protocol with a program and do scroll until you come to PPS."  The program is set to open these files the right pair?  Otherwise, click on edit and then select the correct one from the list.  If is not correct in the list, click Browse and look for the programs executable file in your Program Files folder.  It will probably be under Microsoft Office, but where possible folder names vary depending on your version of Microsoft Office and you don't provide that.  I use Office 2007 and it is located in the Office12 folder.  The file name is powerpnt.exe.  Select the file and set it as the new default value and click OK.  You should now be able to view files and attachments PPT.

    If there is no pps file type listed, then open Notepad (start / all programs / accessories / Notepad) and type Test, and then save the file to your desktop.  Then change the name of the file extension .txt in a .pps extension.  Then right-click on the file and select open with.  Choose the PowerPoint program you use (you may need to scroll down again to the actual executable file in Program Files) and when he requested, check the box for always open these files with this program.  Who should the association for pps on the right program and you should be able to open attachments and files without problem.

    If not, what e-mail you program use (name and version)?  This will tell me where you refer for further assistance by experts on this program.  Here is that links to some programs commonly used - post back if you use another thing, or repost your question in the discussion group or Forum adequate messaging to get help.

  • I'm trying to see the attachments to emails and sometimes it says "go to set associations Control Panel and I can't find it on my computer.

    I tried the Bitware software and resque trying to clean my registry and we tried to search and also google to find the pane control set associations indicating my problem is there, but since I can't find the associations together I don't know if it would help me to be able to view my pics that are sent as attachments. Some of the accessories have worked in the past, but now I had the sender to send again and they still does not work.  Some attachments work, but not ones I've tried before.  3 of them that I can't see has worked in the past, but now they do not work

  • How can I fix an error message telling me to an association in the control panel so I can get email brochures sent to me .___error message in the email

    I get an error message sent to me when I try to pull up different sent pamphlets the error indicates that this file does not have a program associated with it to perform this action, Create and association in the Panel of the Association.  I have not the slightest idea of what it means and its quite annoying can someone help me.

    What I had was the .doc extension.  Go to start / Default programs / associate a file or Protocol with a program / and find the .doc extension.  It is associated with a program that can open and read .doc files (such as MS Word or Word Viewer or write OpenOffie)?  If this isn't the case, you will need to install one of these programs to establish the association and allow you to read the prospectus.

    If you already have one of these programs and the association is already in this program (and you can open .doc files other ways except these brochures by email), then it may be something wrong with your email client or Microsoft Word program.  It is also possible, there is something wrong with the flyers - can you open other accessories .doc in your e-mail program?

    I can't refer you to help with the e-mail software because I don't know which you use; However, you may need to repost your question in the Discussion of the Office group at: http://www.microsoft.com/office/community/en-us/default.mspx?dg=microsoft.public.word.docmanagement&lang=en&cr=US where issues of speech specialists will be more than happy to help you with your problem.

    If your e-mail client is Outlook, send to: http://www.microsoft.com/office/community/en-us/default.mspx?dg=microsoft.public.outlook.general&lang=en&cr=US where experts in Outlook will be more than happy to help you with your problem.

    I hope this helps.
