Apply the variable definition in the subclass with abstract method

Hello

It's his practice use? :
public abstract class Base {
    private int importantPrivateVariable = setImportantPrivateVariable();
    protected abstract int setImportantPrivateVariable();
}
I want to apply the extension of the class to define a private variable, but there is no variable abstract in java, I can use a method for that.

Thank you

Edit: the variable can be protected as well, I guess that's not important here, but correct me if I'm wrong

I don't think it's so common, but it's easily understandable code. However, there are several problems with this approach:

public abstract class Base {
private int importantPrivateVariable = setImportantPrivateVariable();
protected abstract int setImportantPrivateVariable();
}

I want to apply the extension of the class to define a private variable

This is some what your code implements: your base class requires the subclasses to return an int value, and the Base class uses this value to assign to the variable.

Therefore, the method should be called to (for example getInitialValueOfImportantVariable()+ to have a consistent naming with his signature (it returns a value, whereas a regular setter must declare a void return type: protected abstract void setImportantPrivateVariable (int someValue);).)

Edit: the variable can be protected as well, I guess that's not important here.

Well, Yes, it is 'important' - at least, there is a noticeable difference: the variable is private, the base class is free to treat it as seems it (for example, assign the value at construction time and never change it later). If the variable was protected, the subclass could change in ways and at times not known by the base class.

but correct me if I'm wrong

There is a trap in this construction: the method is called in the variable initializer, i.e., behind the scenes, about during execution of the Base, so before the constructor of the sub-class class constructor. For example, you call a method on an object that is not completely initialized (for example some of its attributes may always be null at this point). There is a rule that discourages this kind of situation, which goes something like "no calling private and unofficial constructor methods.

To avoid this trap, two options:
-requires an int argument in the constructor of the Base class, as suggested above
-Don't be and set the value of the important variable in the code of the initializer or the constructor, but a special method in the base class instead:

public abstract class Base {
    private int importantPrivateVariable; // default value is zero
// or alternatively:
//    private int importantPrivateVariable = ...; // Some default value
    protected abstract int getImportantPrivateVariable();

    public void initializeImportantPrivateVariable() {
        importantPrivateVariable = getImportantPrivateVariable();
    }
}

This construction is a degenerate form of a common model known as the model method (where a base class method calls usually several methods of the subclass in a specified order and with a specified sequence, allowing for the subclass to implement the details of the methods).

The downside is that the client code (the one that uses the Base instance) must know when to call this initialization method, while initialization, a constructor-based allows the free client code of don't like do not at all.

Much luck,

J.

  • Install RAC 11 GR 2 and apply the patches with the new Option of software updates YES

    Anyone tried the installation with the new Option of software updates?

    I'm going to install grid RAC 11 GR 2 and I intend to do the following steps:
    (1) install the Oracle Grid Infrastructure 11.2.0.2 patch group
    (2) make all configurations with YES
    (3) create ASM disks
    (4) install Oracle Database 11.2.0.2 software only
    (5) apply recommended patches 11.2.0.2.2 Oracle (12311357) and 12431716. (Ref. MOS doc [756671.1 ID])
    (6) create the RAC (advanced option) with DBCA database

    With these steps:
    Grid and ASM disks would be configured without the recommended patches, but the database will be created with applied patches.

    I would not do a "Software only" install IM and then apply the patches because later I would have to manually do all the configuration steps.

    If I use the Option of YES software updates to apply patches, YES makes the adjustment, and then I would set up the GRID with YES?

    Quote from Oracle® Setup Guide Network Infrastructure 11 g Release 2 (11.2) for Linux - E17212 number of part-11:
    'Use the feature of dynamic download and apply software upgrades of software updates as part of the installation of the Oracle database. You can also download updates separately using the downloadUpdates option and later to apply during installation by providing the location where updates. »

  • Apply the Image with layer.id or layer.itemIndex

    Hello

    I want to use the 'Apply Image' function in my JavaScript.
    Because this function is not available in API, I recorded with the 'ScriptListener.8li' function calls
    Here is the code that was generated (I reformatted the code a bit to make it more readable):

    function testIt() {
        var ref24 = new ActionReference();

  • Passing of Arguments to the Bean with EL method

    Hello:

    11.1.2.3 Jdev

    I created the following managed Bean (see below) in a taskflow with scope of Backing Bean. I can call fieldColor ok with
    EL as in #{backingBeanScope.CheckTimezone.fieldColor}-> works ok

    But now I want to pass a string value to the testDate method and returns a string. What is the El to make this work?
    I tried:

    #{backingBeanScope.CheckTimezone.testDate ('someString')} but it does not work and said testDate is not recognized.

    What is the correct way to call this method by passing a string arg?

    Are there articles that explain this?

    Thank you very much...





    public class CheckTimezone {}
    private String fieldColor = "in late';

    public CheckTimezone() {}
    Super();
    }

    {} public void setFieldColor (String fieldColor)
    this.fieldColor = fieldColor;
    }

    public String getFieldColor() {}

    public String testDate (String subsist) {}
    System.out.println ("called testDate, passed in value is:" + stand);

    In case, you can create a property testDate in your bean that returns a map object.

  • problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

    Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

    Some basic information:

    I work at a seller who needs from one site to the other tunnel.  There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system.  I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range.  So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator.  The hosts behind the tunnel use 20x.x.x.x public IP addresses.

    My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper.  The seller sees my packages and provider host meets them and sends them to the tunnel.  They never reach the external interface on my Cisco router.

    I'm from the external interface so that my endpoint and the peers are the same IP address.  (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.)  Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

    I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host.  Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel.   The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel.  The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

    The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

    Here is what we have done so far:

    (1) confirm the config with the help of Cisco 2811.  The tunnel is up.  SH cyrpto ipa wristwatch tunnel upward.
    (2) turn on Nat - T side of the tunnel VPN landscapers
    (3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
    (4) successfully, tunnel and reach a different configuration hosting
    (5) to confirm all the settings of tunnel with the seller
    (6) the seller confirmed that his side host has no way and that it points to the default gateway
    (7) to rebuild the tunnel from scratch
    8) confirm with our ISP that no way divert traffic elsewhere.  My gateway lSP sees my directly connected external address.
    (9) confirm that the ACL matches with the seller
    (10) I can't get the Juniper because he is in production and in constant use

    Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

    Options or ideas are welcome.  I had countless sessions with Cisco webex, but do not have access to the hub of the seller.  I can forward suggestions.

    Here's a code

  • How to apply the Conversion Table of file FM.

    I have a conversion table generated for a group of files that I am trying to structure. I want to be able to apply the conversion with Extendscript table. The script that I have does not save any file converted. I don't know why is it not save the file. I was under the impression that the "Structure Generator" should create the new file. If this incorrect.

    Here is the code I am using.

    var myFile = File.openDialog ("Select File to Convert"); 
    
    var myCT = File.openDialog ("Select ConversionTable"); 
    var CT = openFile (myCT.fsName, 0); 
    
    applyConversionTable (myFile.fsName, CT) 
    closeFile (CT);

        var name = fileName.replace(/[\w\.]+$/,"test.fm")  
        CallClient("Structure Generator", "InputDocId " + doc.id);

    function closeFile(doc){ 
        Constants.FF_CLOSE_MODIFIED = 1; 
        var res = doc.Close(Constants.FF_CLOSE_MODIFIED); 
    }
    

    Ah, found the problem. I noticed this earlier, but do not think that it was important, it apparently. The other arguments must be all uppercase. Like this:

        CallClient ("Generator of Structure", "INPUTDOCID" + doc.id);
        CallClient ("Structure Generator", "RULEDOCID" + CT.id);
        CallClient ("Generator of Structure", "OUTPUTDOCNAME" + name);
        CallClient ("Structure Generator", "StructureDoc");

    I tested it and it works for me. FWIW, I think that it is a poor quality of a client API feature otherwise very slippery.

  • Applying the 10.2.0.4 group patches of database with compatible version tables

    Recently, we have applied the 10.2.0.4 group fixes database to a database where we had a few tables compatible version. Applying the patch Group took a little longer than expected and flipping through the newspaper, it took about 30 minutes to upgrade the Workspace Manager.

    1) I know in the past that the Workspace Manager patches were separate from patches of the database. MetaLink NOTE: 341353.1 "Why the Workspace Manager version is different from the current version of the patches RDBMS group" seems to indicate that it is no longer the case,

    >
    From group fixes version V10.2.0.4, the Oracle Workspace Manager updates are integrated with the RDBMS patchsets credits.
    >

    But this statement seems to be a secondary element in a document clarifying a distinct behavior. Y at - it another document (Metalink or otherwise) who deals directly with this change?

    (2) someone has a good feeling for the purposes of how long this and future patchsets should take when there are potentially large tables compatible version in the system? I'm hoping / assuming that it is not a linear relationship, because the tables in compatible version, we have at present are rather small. But I don't know if the upgrade time is basically a constant or if there is a dependency on the size of the tables compatible version, the number of tables compatible version, etc.

    I fear that we may end up with very large tables compatible version which would require significant downtime when we apply future patchsets if we Workspace Manager of bugs. I hope / expect that this isn't the case, but I would check a second time thinking.

    Justin

    Hi Justin,

    #1. I couldn't find another document which deals with this, but I can just be missing it. I see if there is something else and let you know if I find anything.

    #2. There are some fixed and variable upgrade for Workspace Manager. Fixed potion RECOMPILE all packages/views, change the tables of metadata, etc. used directly by Workspace Manager. Another potion is made for each table enabled version. First of all, the view and maintained by Workspace Manager triggers are rebuilt. It is usually a fast operation, because it is not dependent on the size of the table. There is also the potential of migration of data for each of the rows in the table with version. If necessary, it would take much longer time, but this type of migration has not been required since version 9.2. If you are upgrading from a version newer than this, this part of the migration would be unnecessary.

    Kind regards

  • structure of the event with a local variable

    Hello world... I tried to make a simple program with the structure of the event in Labview.
    I need to show a value in a table, when an external signal changes its value. (I read a lot of discussions and many documents and I don't understand the thing... Sorry)
    I want to say that I am getting a value of temperature of a sensor in a controller, it works in asynchronous mode sensor, so that the detector Gets a new value in different sampling rate.
    So the PLC program changes the State of a Boolean variable simple that in Labview, indicates that there is new data (newdatareceived---> 1,0,1,0,1,0...)
    I need this draw Labview (valuereceived) value in a chart when this variable (newdatarecived) changes.
    My problem is that the table always puts a value according to the cycle time in its loop and resumes the values... (I tried, with dynamic events and signage value... and I got the same result... It works fine).
    Thanks in advance.

    And the other way:

    Thanks for your time again.

    I've been doing a little test with xygraph and the example works now (thanks!) but I have a doubt, is this the right way or is there a better way?

    No, this code is meaningless. You write new (mostly the same!) points to the graph xy with each iteration (actually at twice the speed at which data can actually happen: 100 ms vs 200ms!), tax system unecessarily and more internal data structures like crazy.

    All you need is a simple loop with a single structure of matter which is true if the Boolean value is different from the previous iteration. Currently, you must add a point (the time for X, the value in Y) to the xy graph. Here is a quick sketch. (You can either use the meter or the elapsed time for X, according to your needs, so change if necessary).

    Events are mainly for the interaction with the user in order to avoid the loop turn unless necessary. Here you are already running a loop to interrogate the instrument and you can easily have the graphic way the same loop. Right?

    You should also be aware that the execution order is determined by the flow of data and not in a horizontal position. If it's important that OCX nodes running first in an iteration, you create a dependency of data (for example with the wire of the error). Horizontal compensation has no effect. The structure of sequence on the left has also does no work, then why is it there?

  • Update Windows shows about 100 updates important to apply. How would you recommend I do. I'm afraid to apply the patches to 100 at a time. Those who would be safer to start with? Thank you

    The manufacturer has replaced the HD on my computer laptop 64 bit Windows 7.  Update Windows shows about 100 updates important to apply.  I can't find patches that I had previously applied in the list of applied hotfixes or patches to apply list.  I don't understand why this is.  How would you recommend I do.  I'm afraid to apply the patches to 100 at a time.  Those who would be safer to start with?

    Thank you

    Hello

    I suggest you only begin to install the important updates (recommended) first and later if you want you can install optional updates. All Windows update are safe to install and it is important to install the update and recommended by Microsoft. It keeps your computer safer and your software current to date and if you want Windows to install important updates as they become available, turn on automatic updating. Important updates provide significant benefits, such as improved security and reliability. You can also set Windows to automatically install recommended updates, which can address non-critical problems and help enhance your computing experience. Optional updates are not downloaded or installed automatically.

    For more information, take a look at the following link:

  • When I apply the criteria to view it doesn't work, but when I apply it through query it works. What is the problem with my approach?

    Mr President

    If I ask a condition through my option of criteria of view vo it doesn't.

    vc.png

    The result is that it doesn't.

    vc1.png

    And if I apply a condition through my query vo option it works.

    vc2.png

    The result is ok as follows when I apply vc in query

    vc3.png

    What is the right way to create a vc.

    Concerning

    The first thing that seems unfair, is that I don't know what version of jdev you use.

    If I ask a condition through my option of criteria of view vo it doesn't.

    and the image below, I do not understand. I see a view Definition of criteria dialog box but not when you apply the criteria.

    the third image shows the definition of criteria, but I don't see where you apply it to or source of dialogue.

  • Cannot export the media with the applied effects

    Hello! I am a new user of first and have encountered a problem where I can not export successfully to the media if I have applied effects.

    I'm recording play me video games, with my webcam video in the upper left corner. The games are sometimes super dark, and I'd like to clear up everything except the area where is my webcam images. I figured out how to do this, but I have to do something wrong.

    Whenever I'm ready to export to the media, he might get 4% and then lock the entire computer. This happens on several different machines, even if I allow export to run all night. If I remove one of the effects (light effects), it exports very well and takes what seems to be a reasonable amount of time. The computer I use is again this year with 32 GB of RAM and a decent video card.

    My sequences are about 30 minutes to an hour long, with one or two tracks audio. The only effect that I add is effects brightening, with 1 light on a Type of directional light and intensity set between 15 and 30. I use a reverse mask 4points polygon to apply the effect to all except the corner with webcam images.

    What I'm doing wrong! I googled several times and can never find an answer.

    Thank you all very much for your time.

    Hi Tom,

    Sorry for your troubles, first.

    If I remove one of the effects (light effects) , it exports very well and takes what seems to be a reasonable amount of time. The computer I use is again this year with 32 GB of RAM and a decent video card.

    What I'm doing wrong! I googled several times and can never find an answer.

    Thank you all very much for your time.

    You are doing nothing wrong. In fact, we are in error. This is a bug. This bug has been marked as fixed for our next release, if. It should be OK to use it in the next release, which is scheduled for release very soon. For now, try another effect, as the fast color corrector > input levels sliders.

    Hope that helps.

    Thank you
