• How to access the inner class fields in refleciton?

  I have:

  I use reflection to get the Outer.field field and recognize that it is a reference to the inner class. What should I do to get the inner.field (or something that looks remotely like this at Inner.field)?

  Well, precedent is too messy for me even follow my example. I've simplified it, and I think I found where my error was. I suspect that you were doing a similar error:

  package scratch;
  
  import java.lang.reflect.Field;
  
  public class Scratch {
  
    public static void main(String[] args) throws Exception {
      new Scratch().go();

        System.out.println ();
  
        System.out.println ("field.getClass()) : " + fc.getName());
        System.out.println ("field.getClass().isMemberClass() (" + fc.getName() +" isMemberClass()) : " + fc.isMemberClass ());
        System.out.println ("field.getClass().getDeclaringClass() (" + fc.getName() + "'s declaring class) : " + fc.getDeclaringClass ());
  
        System.out.println ();
  
        System.out.println ("Note the difference between Field.getClass() (" + field.getClass () + ") and Field.getType() (" + field.getType() + ")");

    }
  }
  
  class Outer1 {
    class Inner1 {
    }
  
    Inner1 i1;
  }
  
  Outer1 field : i1
  
  field's class (field.getType()) : scratch.Outer1$Inner1
  field.getType().isMemberClass() (scratch.Outer1$Inner1 isMemberClass()) : true
  field.getType(). getDeclaringClass() (scratch.Outer1$Inner1's declaring class) : class scratch.Outer1
  
  field.getClass()) : java.lang.reflect.Field
  field.getClass().isMemberClass() (java.lang.reflect.Field isMemberClass()) : false
  field.getClass().getDeclaringClass() (java.lang.reflect.Field's declaring class) : null
  
  Note the difference between Field.getClass() (class java.lang.reflect.Field) and Field.getType() (class scratch.Outer1$Inner1)
  

  field.getClass () does NOT get the class of the field. It get the class of the field object that points to the field reference variable, which is always java.lang.reflect.Field. To get the class of the field, use field.getType ().

  Do you see the difference?

• 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.

• Creating objects of Inner classes

  public class Test{

  I want to make a new instance of the inner class. I tried to make the static inner class. I tried to call like this: classObject.forName ("OutterClass.InnerClass");
  
  Anyone know what I am doing wrong? Thank you.
  
  Also, how can I set parameters to the constructor by using the newInstance() method? It would be like this: newInstance ("Hello World")
  Example:

       public class InnerTest{
            public InnerTest(String s){
                 System.out.println();
            }
       }

  Thanks for the help. I appreciate it.

  Without knowing all the details of your mission, not to mention the total number of internal classes available, could you not do something like:

  //read file
  
  if("InnerClass1"){
    //create InnerClass1 directly
  }
  // more if-conditions...
  }else{
    System.out.println("Invalid inner class...");
  }
  

  And then you don't have to worry about trying to find the correct constructor to be used by reflection.

• Unable to make a call to the custom class

  Hi all

  I train to call the custom since the screen as below class, but its not picking up the custom class features and gives the result, I don't know if something is not in the below class or the way I call this method.

  I suspect that your problem is the LabelField don't think it has any text to display.

  You really need this, I think

• Anonymous inner class

  Hello

  I'm building a custom menu system and I'm using an anonymous inner class with a method of execution. Can you tell me how to run the run method... thx... Here is a code example.

  Simon, I thought about it... I had to implement Runnable in the class, which allows me to call the method run like this:

  No.... These int values not the type of display object attributes. These integers is the index of attributes.

  To determine the type of the VO attributtes, you should see the Get accessor of the attribute and the setter

  as

    public void setCountDockets(BigDecimal value)
    {
      setAttributeInternal(COUNTDOCKETS, value);

  This means that the attribute type CountDockets BigDecimal

• Two quick questions (hopefully) - right way to dynamically change the CSS class and put of Splash screen implemented

  Couple of quick questions have left me speechless!

  So, it seems obvious that many JavaFX applications want to dynamically change the CSS styles.  Is the best way to do it through la.getStyleClass () .add ("classname") < node >?  The underlying data structure is a list of observable.  So let's say we have 5 styles that simply to change the fill color of a circle of 5 different colors, respectively.  So if I have a condition in which I want to dynamically apply 1 of these 5 styles, as I do now it's by setting all 5 styles as a string in a list by using a static initializer, then I call < node > .getStyleClass () .removeAll (list), then getStyleClass () .add ("classname").  I do this to avoid adding again and still the same style and inflate the underlying list.  What is the right way to manage dynamic CSS styles?

  Finally a very simple I think.  So I know there's a little differently to implement a splash screen.  My app has certainly got bigger in the last few months of development and I noticed there are about a 5 second delay between when I run the application when I see the main stage.  I was thinking what a splash screen would be nice to fill that time.  I had no time to prototype using a Preloader and I fear that using another, early stage start-up again would be too long of a delay.  "I actually thought that using the Nice and simple JVM argument" - splash: image name > "would be simple, easy and effective.  Unfortunately when I try to do, the splash screen appears but never goes away.  Anyone know what is happening with this?

  Your mechanism to manage the css style classes is a good approach; I've used several times. I wonder why the style classes have been implemented as a list, instead of a game, but there may be cases of good use for the use of a list.

  In some cases you can also consider using CSS PsuedoClasses, which were presented in JavaFX 8. Here is a little easier to use, especially if you have two options. But a use case might look like:

  public class Message {
      public enum Status { NORMAL, WARNING, CRITICAL }
  
      private final ObjectProperty status = new SimpleObjectProperty<>(Status.NORMAL);
      private final StringProperty message = new SimpleStringProperty();
  
      // constructor, getters, setters, and property accessors....
  }
  

  public Label createLabel(Message message) {
      PseudoClass warning = PseudoClass.getPseudoClass("warning");
      PseudoClass critical = PseudoClass.getPseudoClass("critical");
  
      Label label = new Label();
      label.textProperty().bind(message.messageProperty());
      message.statusProperty().addListener((obs, oldStatus, newStatus) -> {
          label.pseudoClassStateChanged(warning, newStatus == Message.Status.WARNING);
          label.pseudoClassStateChanged(critical, newStatus == Message.Status.CRITICAL);
      }
      return label ;
  }
  

  And then your css looks like

  .label:warning {
      -fx-text-fill: orange ;
  }
  .label:critical {
      -fx-text-fill: red ;
  }
  

• The JavaFX class hierarchy

  I have a question about the architecture of the JavaFX class. In fact, she should follow the pattern of composite named design looking for this http://en.wikipedia.org/wiki/Composite_pattern way somehow.

  However if I want to draw the composite model of the JavaFX package I find myself sort of this way:

  

  It seems that I can add children to buttons or labels. It was also possible with SWING. Why it has not been repaired? Is this a feature? On the other side window and the steps are now outside the model. In fact, they should be Parents I think. Why is it designed this way?

  Hope someone can enlighten me upward. Thank you very much for your answers in advance.

  > Actually it must follow the model of composite named design somehow.

  I think you are trying to simplify things.

  The JavaFX scene graph is a composite structure, but its design is subtler than a model composite vanilla.

  The basic concept of the presentation of JavaFX is a scene graph.  A scene contains a node tree, which forms the scene graph.  Any node that is not a leaf is a parent.  The parent base has a public method getChildrenUnmodifable and a protected getChildren method.  This means that you cannot add outwardly new nodes to a Parent unless you provide additional APIs.  The only thing that can add children to the mother is the Parent or the subclass of the Parent.  So, there's some cache information to go on.

  Some subclasses that act like editable containers expose their list of children to be publicly editable.  Usually, this is done by providing a public getChildren method.  A component, which is the root layout manager class, so in general, you can change the children of any pane layout is an example of such a class.  Conversely, if you have something that does not expose its getChildren method publicly, then external components cannot directly change the children of this thing.

  Region and the control are examples of nodes that extend from Parent and do not provide a public API getChildren.  As a button is a control, if you can not directly change her children through the public API.  The only way to change the control's children is to provide your own skin or to use additional modifier of APIs that control could provide.  For example, a button can have a chart, you can set the button and thus provide an arbitrary node or node tree to the button.  However, that is not quite the same Exhibitor getChildren button, because the graph is just a node, and layout in the button can be handled by the button through the display of the content of the button setting.

  OK, so JavaFX should not have had this complexity.  He could really go for a simpler approach where everything is a node, there are only a few types of nodes and HTML node types are not extensible example.  But he did not do this.  Instead, he went for a more detailed breakdown of the nodes of types, with each type supported by an object model providing State and functionality.  It's just a different approach.

  > It seems that I can add children to buttons or labels.

  Have you tried to do this by calling getChildren on one of them to get the list of children so you can change?  I bet that you could not do.

  > Window and steps are now outside the model.

  Yes, they are not part of the scene.

  All this is just a metaphor for the theatre.  Imagine that you go to the theater to watch Romeo and Juliet.  You sit in your Chair and watch the scene, the curtain has just unveiled the first scene.  The scene contains a background (a square of city to Verona in Italy), some accessories (swords and a fountain) and actors (nobles) who move and speak and go away.  These things in the scene are the nodes of the scene.  The curtain goes down and another scene appears, then again and another scene.  Finally, you arrive at the scene of the balcony where Romeo climbs the wall to join Juliette.  Whenever the curtain goes down, a new scene is assembled, and when the curtain rises the new scene appears.  All the time, the scene never changes.  This isn't a part of the scene.  The scene is the scaffolding in which many different scenes will appear.

• Change the value of "int" one within the arraylist class instance.

  It's my program...

  Now, I want to change the value of "int a" within the first class of the table

  Well, nothing of this code will compile, but if you corrected the errors, and that was the case, you can replace it with

  hello.get(0).a = 123;
  

  But what you should really do is read all the tutorials you can find.

• Cannot filter data with the extended class

  Hello
  
  I have a small question on the PortableObject format. I created a class that extends PortableObject interface and implementation of methods of serializer as well. I've updated in the file config.xml - pof as well. If I insert the objects of that type of object in the cache, they get inserted correctly and I can filter the values based on the getters defined in the class. Everything works fine here.
  
  Now I'm expanding the existing class I. We have our custom API we have built for our domain objects. I need to store these objects in the cache. So, naturally, I need to implement the PortableObject interface for this. So, instead of creating a new class with the new series of getters and setters and local fields, I extend our domain class to create a new class that implements the PortableObject interface. Instead of setting the local fields and getters and setters, I'm reusing those provided by my existing class. Now, I can insert the new class objects in the cache. But I can't filter values for objects of this new class.
  
  Let me show you what exactly I am trying to achieve by giving a small example:
  
  Domain class:
  
  Class person
  *{*
  private String person_name;
  
  * public String getPerson_name() {return person_name ;} *}
  * public String setPerson_name (person_name) {this.person_name ;} person_name = *}
  *}*
  
  The new class that implements PortableObject interface:
  
  class ExtPerson extends implements person PortableObject
  *{*
  public static final PERSON_NAME = 0;
  
  * public Sub readExternal (PofReader reader) throws IOException {*}
  setPerson_name (reader.readString (PERSON_NAME));
  *}*
  
  * public methods void writeExternal (writer PofWriter) throws IOException {*}
  writer.writeString (PERSON_NAME, getPerson_name());
  *}*
  
  * / / And HashCode, Equals and ToString methods, all implemented using the Get accessor of the person class *.
  *}*
  
  So, if I create a new class ExtPerson extend the Person class and write all methods, store objects in the cache and run the following query, I get the size printed
  
  System.out.println ((cache.entrySet (EqualsFilter ("getPerson_name", "ABC"))) .size ());
  
  But if I use the extended class and insert the values into the cache and if I use the same query to filter, I get 0 displayed on the console.
  
  System.out.println ((cache.entrySet (EqualsFilter ("getPerson_name", "ABC"))) .size ());
  
  So, can anyone say exactly what is the cause?
  
  
  Thank you!

  ContainAnyFilter doesn't work the way you expect.

  Here's the java doc.

  "Filter that tests a value of Collection or array object returned by a method of containment of any value as a whole."

  The return of the object by the get method must be an array of Collection or an object, it will return false if the object of the return of Extractor is not a type of Collection or array.

  or in your case, it only works if the getPerson_name() returns an array of strings.

  You probably want to use talk.

  Any ideas of what the problem may be Pls?

  Hi Bfab,

  When you get this error message exactly? You see that at the end of the installation during installation or recovery?

  I used the disk recovery from my laptop, very often, but never had a problem with it. It s still works correctly.
  If recovery disk doesn't work, it could be a malfunction of the equipment.

  Have you tested a normal disc of Microsoft Vista too?

Also does not count calories for example 35 when the average of the others in the group is around 500.

  Hello

  When you use the application of the training session, choose the type of activity that best fits your business. For anything else - like weight - select the other category.

  During the follow-up of one year to the next helps:

  • Activity app will credit the ring of progress of exercise with one minute for every minute of the workout.
  • Active calories will be based on the data recorded by the heart rate sensor or a brisk walk, whichever is greater.

  Note, however, that the heart rate sensor is likely to give better results for the workouts that involve rhythmic (for example running) rather than the irregular movements.

• With the help of the child in the executable class

  I'm kinda stuck and don't know how to solve and could not find a solution online.

  I have a parent class and its children to the class. The child class only overrides a method, but not the run method. I want to compile the executable project, where the run method is called, but the class type is the child, not parent. How to do this?

  I tried three things, but all in vain:

  (1) in the build properties when I select start VI the run method of the parent, I get in the executable the parent, not the child's class class. It's logical. However, I couldn't find the option to use the child as a type's class.

  (2) when I add the run method of the child class and appeal to parents, I get two windows pop up. The run of the parent and the child method. Too many. Even if for the class child run method (see below the block diagram of a child, red run method's parent), I put not to show the façade when it is called in the properties of VI.

  

  (3) when I tried with a separate VI calling the run method of the parent class, but the class type is the child, I get the façade of this separate VI and the run method of the parent. See below (Blue class is child, red of parent).

  

  In both cases 2 and 3, I chose to put the checkbox 'See the façade when it is called' a FAKE, but still the front panels appear.

  Someone don't know either: i) the use in the executable version of the options to generate an executable when a different class method is used, or ii) when you compile an executable file with a certain start VI, to not show this starting VI?

  I understand if I say "you want to configure the RUN method of the class as 'start-up VI' in the EXE file, but it should run the RUN method for a child object"?

  If this is correct, your third approach is the right one. This new boot VI is often used as 'Splash Screen' that covers the task of a demon "spawning" for your application.

  You must simply close this VI once it's over. This can be done using VI server on its own front panel functions.

  hope this helps,

• Substitution of the class, how to create the child class and then the base class

  I started to write a program for a DMM smart, that the problem is all versions of DMM greet the change company communication.

  My idea is to write a child class for each version, DMM and each Subvi child will replace the Subvi base class.

  My problem is, I first want to create a child class and after I see everything is working, start creating the base class. in this way, I'll see if think the right way.

  My question is

  How can I create a child class and then create the base class and configure the Subvi class of the child to be the substitution of the base class?

  I tried searching in the property of the class, but I don't see anything.

  Thank you

  This can be done and I did on occasion.

  You create the base class with the methods of dynamic distribution, you need (Connector components must be identical to those of the class of the child).

  Set then the legacy of the class inherits this base class.  If your method is defined as a dynamic distribution method in the parent, you will probably now have some errors (unless your method of child was already DD, in which case you might be OK already).

  To change the inheritance of a class, right-click on the properties of the class in your project, and then select Properties.  According to me, the tree of estate is at the lower end of the property.  Click on the 'legacy of change' (or something similar) to choose the class from which you now want to inherit.
