• Pass a variable to the main class to a MovieClip

  Hello!

  I have a document with the main class.

  I have also a few clips that have their own class and functions.

  I'm trying to pass a variable in my main class to one of these clips.

  I tried a few things, nothing has worked.

  Who can help?

  Match_Easy looks like a class name.  You must use the name of the instance.

• Dynamic release of variable size of dispatch class method array on FPGA

  I have a parent on the FPGA class that will serve as a model/framework for future code which is developed. I had planned on creating a class of the child and by substituting a few methods. The child class constant would have fallen on the schema so that the compiler would have no trouble knowing which method (parent or child) should be used (i.e. the parent method will in fact never used and will not be compiled with the main code). The output of one of the methods is a table. This table will have a different size depending on the application. I set the size of array as a variable. In the method of the child, there is no doubt about the size of the array so that the compiler must be able to understand. However, when I try to compile, I get an error on the size of the array. I can't figure a way around it. Any thoughts would be greatly appreciated!

  Thanks, Patrick

  

  The question implies the use of the register shift unitialized. On the first iteration of the loop, the value that comes out of the shift register is the default value for the data type, which is an empty array for a table (size zero). Therefore, unless wire you a table empty for the shift register to the right, the size of the array cannot infer statically by the compiler.

  To resolve this problem, you must feed an initial value for the table. Here, I just used the function of the matrix, but if you need to have a separate method that returns an array of default or the size of the array that will work as well.

  

• Modify a variable in the adapter class

  Hello
  
  I have deployed Hello world app and I see that there is a variable such as "message". And this has been defined in the assembly EPN as instance-other property file.
  

      <wlevs:adapter id="helloworldAdapter" class="com.bea.wlevs.adapter.example.helloworld.HelloWorldAdapter" >
              <wlevs:instance-property name="message" value="HelloWorld - the current time is:"/>

  How can I change a variable of a class of runtime adapter?

  Hello

  I'm glad you have work. I was thinking something much lighter, API-wise, in the sense of article 22(2) in Spring 3.0 documentation. You simply create a Spring bean and then export it using the JMX exporter.

  http://static.SpringSource.org/spring/docs/3.0.x/Spring-Framework-reference/HTML/JMX.html

  I just wanted to mention that as an another possible option. Remember that AbstractStageMBean is not a public API.

• equivalent of variable static visual Basic in LabVIEW

  Hi all!

  I am doing a project where I count values. After I farm/Stop the program I want the value to be intact and continue with the last value.

• fieldChange get variables from the main class

  I'm doing a simple calculator that users enter numbers, press on calculate, and the answer is displayed in the status bar.  The problem I have is that when I try to get the EditFields values in the fieldListener, I get an error that says that the variable was not found.  Here is an example of the code that I have:

• Get the value of the bind variable in backing bean class VO Impl

  Hello
  
  I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:
  
  /**
  * Returns the value of the variable to pOrgId.
  value of the variable * @return for pOrgId
  */
  public {getpOrgId() number
  return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
  }
  
  So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).
  
  (JDEV 11.1.2.3.0)
  
  Concerning
  Carl

  Hello

  When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
    Object returnVal = oper.execute();

• Unusual use of the static getInstance factory class definition interface

  This question is prompted by a recent new to Java forum question asking about the differences between Interfaces and abstract classes. Of course, one of the standard things mentioned is that interfaces can't actually implement a method.
  
  One of my former clients, the 500 group, using interfaces as class factories. The interface defines a static class of the pubis with a static method public, getInstance, who is called to generate instances of a class that implements the interface.
  
  This architecture was very object oriented, made good use of polymorphism and worked very well. But I have not seen this used anywhere architecture elsewhere, and it seemed a bit convoluted.
  
  Here's a version of 'Nick' of the model of the base interface and use

  -- interface that defines public static factory class and getInstance method
  public interface abc {
      public static class FactoryClass
      {
          public static abc getInstance ()
          {
              return (abc) FactoryGenerator(new abcImpl(), abc.class);
          }
      }
  }
  
  -- call of interface factory to create an instance
  abc myABC = abc.Factory.getInstance();

  1. each major functional area ('abc' in the above) has its own factory of interface
  2. each major functional area has its own implementation of this interface class
  3. There is a generator (FactoryGenerator) that uses the interface class ("abc.class") to determine the implementation to instantiate classes and return. The generator class can be configured at startup to control the actual class of return for a given interface.
  
  I should mention that the people who designed this whole architecture were not novices. They wrote very sophisticated multi-threaded code that rarely had problems, was high performance and was easy to extend to add new features (interfaces and classes of application) - pretty much plug-n-play with little, if any, side effects affecting existing modules.
  
  It is a process of best practices of factory design classes and methods? Please provide feedback about the use of an architecture like that.

  The way he explained to me at the time is that the interface uses standard naming conventions and acts as a template to make it easy to clone new modules: just change 'abc' to 'def' in three places and write a new class of "defImpl" which extends the interface and the new interface and the class can simply 'plug in' to the framework.

  There are in your pseudo code code in the interface to build a new abcImpl(). This deployment of a new plant means a change of this interface. If this is what is meant, it is poor. See java.util.ServiceLoader for an example of the right way to do it, with the implementation classes named in an external file.

  The generator class might use the information, if provided, to provide a new version of the class which would extend this default class.

  I hope so, but who is not exposed by your pseudocode.

  I never saw any 'Java' pattern that looks like this or any model where a contained interface a class.

  There are several examples in the JDK. Unfortunately I can't think of them right now. ;-)

  It seemed really complicated for me

  Me too.

  and it looks like the "versioning" aspect could be accomplished in a much simpler way.

  Indeed, he can see java.util.ServiceLoader.

• get constant static in a class

  Hi, I have this class:

  package cl.mejorencasa.pedido.modelos
  {

  Pedido/public class implements IPedido
  {
  public static const = "en Espera"; ENESPERA:String
  public static const = "Is" ATENDIENDO:String
  public static const = "En Cocina" ENCOCINA:String
  public static const = "Fuera de Cocina FUERADECOCINA:String."
  public static const = "En Camino '; ENCAMINO:String
  public static const = "Entregado ENTREGADO:String."
  public static const = "Perdida por Repartidor; PERDIDOPORREPARTIDOR:String
  public static const = "Pérdida por Cocina" PERDIDOPORCOCINA:String
  public static const = "Cancelado por client" CANCELADOPORCLIENTE:String
  public static CANCELADOPORFALTADEPRODUCTOS:String const = "Cancelado Falta Stock."
  
  

  }

  what I want to do is to create a method that gets all of the constants in this class and return them in an ArrayCollection collection. I must say I want this method to be dynamic, I mean, I want him to go through each constant that are in the class. Myself, I don't wan't to add in an ArrayCollection collection.

  The problem is that I don't know how to create such a method, can someone help me?

  Thank you very much.

  Sebastian Toro

  To view the static, I think you have to pass the class itself, rather than an instance of the class, to describeType(). So try

  describeType (Pedido);

• static text. variable | static text

  I think I need a simple actionscript code to do this, but I don't know exactly. I have a dynamic text field that loads a variable named count. However, I want to place static text on either side of the value of the variable. because the variable is an integer which will only increase, its horizontal width will also increase as well. I can't very well to place two channels of static text on each side of a variable that will grow in width over time. who is?
  
  essentially, I want to have a dynamic text box to display a text string, then the value of a variable (which turns into length), and another string of text, but I would at all be transparent, looking as if I just typed the whole sentence in a word processor. Thanks for your time!

  Let's say you have a dynamic text with instance name my_txt field
  When you want to increase the value, you run my_txt.text ++;
  When you want to decrease the value, you run-my_txt.text;

  now, to convert the dynamic text to a movieclip symbol field,
  the value of the instance name my_mc

  now, we must use to set the value of text,
  my_mc.my_txt. ++ Text;

  but we will not set the value of this way.
  now go to my_mc movieclip, select frame 1, attached script:

  var actualValue:Number = Number (this.my_txt.text);
  var displayValue:String = "";
  function setValue (d) {}
  the actualValue += d;
  displayValue = 'something' + actualValue 'something';
  my_txt. Text = displayValue;
  }
  setValue (0);

  Return to your timeline to mutilate. and now.
  When you want to increase the value, use my_mc.setValue (1);
  When you want to increase the value, use my_mc.setValue(-1);

• Build a class variable value

  Hello

  I am trying to initialize a class based on the value of a variable. I know that I can use the class of thinking in Java, but J2ME does not support this.  Is there another way?

  To give you an idea of what I'm trying to do, I have a main object (UiApplication) passed to all initialized screens. Now this main object has a method named getScreenInstance() that can be called by any screen to get an instance of a screen based on the string, they put in the parameter.

  The point of this is so I can push to another screen at any time without having to re - initialize it if it is already initialized. This might be able to do differently, I am new to J2ME (and kinda new to Java as well).

  If there is a different way, I'd like the solution, although always, I would like to know if it is possible dynamicalled load a class and pass parameters to the constructor it is also.

  Thanks in advance

  Apart from the ugliness, what's not with something like:

  public Screen getScreenInstance( String screen_name ) {
    Screen screen = (Screen) this.screen_registry.get( screen_name );
    if ( screen == null ) {
      screen = makeScreen( screen_name );
      if (screen != null) {
        screen_registry.put( screen_name, screen );
      } else {
        // report unrecognized screen name
      }
    }
    return screen;
  }
  
  private Screen makeScreen( String screen_name ) {
    if ( "ScreenA".equals(screen_name) ) return new ScreenA(this);
    if ( "ScreenB".equals(screen_name) ) return new ScreenB(this);
    // etc.
    return null; // unrecognized name
  }
  

  You might even be able to do something with initializers static in the classes of your screen so that the names of class is part of a register before that all instances must be created (although this puts you at the mercy of the arcana of class loaders machinery).

• Java if statement error: cannot reference a Variable no final inside an inner class defined in a different method

  Hi, I am a newbie to blackberry java development, and I need help. I want to check if my SearchBox is equal to 1, or any other number, but when I try and put this, I get an error, could you take a look and tell me where I'm wrong, and how I can solve this problem.

  See you soon,.

  Max.

   BasicEditField SearchBox = new BasicEditField("Go To Page Number: ", "", 3, EditField.FILTER_DEFAULT);
      add(SearchBox);
      ButtonField myPageButton = new ButtonField("Go to Page",ButtonField.CONSUME_CLICK);
      hfm3.add(myPageButton);
      add(hfm3);
  
      myPageButton.setChangeListener(new FieldChangeListener(){
          public void fieldChanged(Field Field, int context){
          if(SearchBox.equals("1"));
              Page1 Page1 = new Page1();
           UiApplication.getUiApplication().popScreen(Ui.getUiEngine().getActiveScreen());
           UiApplication.getUiApplication().pushScreen(Page1);
      }});
  

  If you want to access a local variable in an inner class you must make final.
  Another option would be to declare the variable in the class.

  Another thing: Searchbox will equal never '1', you need to use getText to return the text of the editfield.

• How to pass a variable between classes?

  Hello

  I created a class .as MovieClip to a MovieClip that contains 7 buttons. I use a table of these buttons and an array of labels of image on the timeline of the MovieClip parent to navigate in the labels.

  ...
  
  private function clickHandler(event:MouseEvent):void 
          {
  //Sets the current button listed in the button array    
   currentButton = MovieClip(event.currentTarget);
              index = buttonArray.indexOf(currentButton);
          
  //Uses the index variable to find the corresponding frame label from the label array            
  MovieClip(root).gotoAndStop(labelArray[index]);
          }
  
  ...
  

  This works perfectly.

  Now I have another .as MovieClip class, I created a simple MP3 player MovieClip. I'm pulling in a XML data of each mp3, including the URL, etc... All works perfectly.

  I'm trying to use the variable "index" of the class Nav.as in the class AudioPlayer.as to play the corresponding number of the song. By calling "playSong (index);

  "playSong (index);" works in a test file, when I tested the navigation tables and the corresponding number xml concept. I need to shoot the variable 'index' from Nav.as to AudioPlayer.as.

  ...
  
  private function playSong(mySong:Number):void 
          {            
              var myURL = my_songs[mySong].@URL;        
          
              if (my_channel) {
                  my_channel.stop();
              }
          
              my_sound = new Sound();
              my_sound.load(new URLRequest(myURL));
              my_channel = my_sound.play();
          }
  
  private function onPlay(e:MouseEvent):void {            
       playSong(index);
          }
  

  It works perfectly when tested. For example: "playSong (2)" or "playSong (5)" plays the song number correct.

  Thank you in advance!

  You should not have a currentIndex in each class, simply on the mother of the other 2 classes. When you say 'this.parent' you access the parent display object. This is where you want currentIndex to exist. If both classes are on the same display list then 'this.parent' will be the same parent and therefore the same variable.

  I didn't know what kind of display object container parent was (MovieClip, Sprite, etc.), so I've referenced it let go like: 'object (this.parent) .currentIndex '.

  Should be in NAV. As:

  Object (this.parent) .currentIndex = buttonArray.indexOf (currentButton);

  AudioPlayer.as should be read through:

  playSong (Object (this.parent) .currentIndex);

• recovery of the external class variables

  I created a class loader that retrieves variables from an external text file. I call the loader class and everything works fine but I can't figure out how to get and use variables in the main class. Can someone help me please?

  Call main class:

  function createInfoText (): void {}

  var loadTxt:LoadTxt = new LoadTxt("text_files/mainTxt.txt");

  }

  Class LoadTxt:

  package app.gui

  {

  flash.net import. *;

  import flash.events. *;

  public class LoadTxt

  {

  private var externalTxt:String;

  public var loader: URLLoader = new URLLoader();

  public void LoadTxt (external)

  {

  externalTxt = external;

  init();

  }

  function init (): void {}

  loadExternalText();

  }

  function loadExternalText (): void {}

  loader.addEventListener (Event.COMPLETE, handlerComplete);

  loader.dataFormat = URLLoaderDataFormat.VARIABLES;

  Case of load data

  Loader.Load (new URLRequest (externalTxt));

  function handlerComplete(evt:Event):void {}

  var loader: URLLoader = URLLoader (evt.target);

  trace (Loader.Data) //this works OK

  }

  }

  }

  }

  I know I have to get the data that is held in the var 'loadTxt' but I'm brain-dead!

  Thank you

  Here are a few things to think about...  The LoadTxt class must have loaded the file until the master file can try to access it.  If the LoadTxt class should be a way to tell the main file, it is ready.  What you could do in your handlerComplete function is hurry up an event for this purpose and have an event listener assigned to the instance of LoadTxt, so that the data can be extracted from it when it's ready.

  You can use the custom LoadTxt class event class to pass data in the event that hurry you, if you won't read about the creation/use supported the transmission of parameters.
