Generic class of packaging a number Comparable and infinite

Hello world!

I want now to implement a class that may as well wrap any class that extends number, is Comparable and has an infinite number of element, which is superior to all others (I know, Float and Double who already, but I need to be able to have whole etc as well).

My current draft looks like this:
public class NumericalAnalysisSet<T extends Number & Comparable<T>> implements Comparable<NumericalAnalysisSet<?>>{

     private Tuple<T, Boolean> value = null;
     
     public T getNumValue() {
          return value.entry1;
     }
     
     public boolean isInfinity() {
          return value.entry2;
     }
     public Tuple<T, Boolean> getValue() {
          return value;
     }

     @Override
     public int compareTo(NumericalAnalysisSet<?> o) {
          int result = 0;
          if (o.isInfinity() && !this.isInfinity()) {
               result = -1;
          } else if (this.isInfinity() && !o.isInfinity()) {
               result = 1;
          } else {
               result = this.getNumValue().compareTo(o.getNumValue());
          }
          return result;
     }
     
}
but my generic stuff seems wonky - the call
this.getNumValue().compareTo(o.getNumValue());
produces an error on o.getNumValue ().

This should be possible, so is there an easy way to fix it? Or do you have another solution for my problem?

Thanks for any help you can give!

    How to set the 1st online number = 10 and increment 10 whenever you press the button to add a new line. Also enable users to enter the generic numbers, IE 13 and still increment of 10 23 or whatever.

    I already have my chart updated in place with a button that will add new lines when pressed.

    Now, I want to clarify that the 1st row is 10 and all the other rows after this increase by 10. It will also allow users to enter any number they want, and the next line will increment of 10.

    Help please.

    Try changing the line button Add the following JavaScript code

    newRow var = Table1._Row1.addInstance)

    If (newRow.index > 0)

    {

    newRow.NumericField1.rawValue = newRow.resolveNode ('Row1 [-1].) NumericField1') .rawValue + 10;

    }

    You need to change this code to match your name on the form, but basically the method addInstance() returns the new row, the newRow.resolveNode ("Row1 [-1]... will get the value of the previous row and then add 10.

  • How he handles the labview to more generic class

    It's just a matter for my own knowledge of curious nerd. If you, say, have a cluster that contains a string, a Boolean value, and a digital control, a common method to reference the controls in the cluster is to create a cluster of reference and then to get the array of control from a property node. So let's say I wanted to put the Boolean value true, you can auto control array index and cast in more specific class boolean and set value via the property node (see below).

    Now my question is, to place controls of different types in a table must be returned by the property node, they must all be of the same class. How LabVIEW manages it? He cast as a more generic class backstage? If so, how this work because it is generally dangerous to come back from a class derived from a base class because the data can or will be lost.

    Furthermore, a standard molded type takes just a binary model and interperates as differently it based on the data type. So how is "of a more specific class" able to raise an error if a generic control reference cannot be transformed into a class more specific. For example, in the attached photo, a control string reference would be mistake out there, but how? They are all classes of generic control when they get out of the property node. Is there some type of indicator in the generic control reference indicating the type? Maybe I think about this fundemtally wrong. All I can think is that the more specific / are more generic vi no type casting (which I guess they are not because it has separate type cast feature).

    Can someone explain how this all works. Inquiring minds want to know.

    I don't know all the details, but I would say you got it mostly right - there is an implicit conversion to a more generic type.  You will see this in several places in LabVIEW, for example, you can wire references to different types of controls in "table to build" to get a picture of their more specific common parent.  Because you're only casting reference - not the data that it contains, there is no loss of data.  A LabVIEW reference is just an I32 is (I assume) an index into a lookup table somewhere.  The value of this I32 does not change when it is converted into a more generic reference.  When you do "to more specific Type", LabVIEW raises this reference in the table and uses the data it found to determine if she can make the cast.  Who help me?

  • Question about cast of more generic class

    I refnum controls and pages refnum and I want to know where is the best:

    (1) let LabVIEW doing work

    or (2) use the 'more generic class type conversion.

    In both cases the VI works fine.

    Thank you

    'that's better... »

    I can't say definatively, but I've generally will do top-cast to build a table that you have illustrated LV.

    EDIT

    I just noticed your case apperas to have 50 more digital cases. What you do with this code? We may be able to offer alternatives (maybe).

  • I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2.

    I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2. My spooler file got corrupted and I need to know what that the stamp of date/time on the latest version of the file: spoolsv.exe. I did a search on my hard drive and found 8 copies of the file with 7 different dates. I need to know which copy in my file C:\windows\system32\. I suspect that the problem was caused by some kind of malware. I think that some of the different versions on my machine of the initial installation of the Vista, SP1 and SP2. 3 copies that would explain. I tried all the suggestions in this forum and several others. I tried sfc/scannow and it simply replaces the corrupted file by another. I understand how works this file and a simple copy will do the trick if I knew that the file to use. I know that I don't want to go back to the first version of 2006.  BTW... my symptoms are all my printers have disappeared, and when I try to 'add a new printer' I get an error message saying that my spooler service does not work. When I opened my services window it shows that indeed, he is arrested, but I will not start because the description column contains only the code garbled machine indicating that the file is corrupted, or it may contain a virus. I had been using F-Prot until this virus got by and now I use AVG. I scanned my machine with several cleaning packages and it is is more infected, but I worry that from this corrupt file grow something. I know that the problem is not with my printers or drivers, because everyone on my home network can print on all of my printers. None of the people I know are on Vista 32 bit. They are all running System 7 or XP. I have XP, except that a few years ago I suffered from the "Syndrome of Pepsi" on my laptop and when I bought a new HP, it came with Vista.

    Hello:
    All the classes necessary to compile your code should be downloaded first using loadjava to the schema of the user or a shared schema, except the classes that are part of libraries JDK1.5 If you use database 11 g, for example the java.io package.
    Once you have downloaded your .jar files that includes your .edu code package will be prepared and resolved OK.
