Passing of Arguments to the Bean with EL method

• Is it possible to pass an argument to the function triggered by an event handler?

  Hi all
  Try to migrate my way of thinking in AS2 to AS3/CS4.
  OK, I have 2 buttons on the stage. Each button almost did the same thing, so I want to create a unique function, and each button calls this function even (we'll name this function 'Navigate')... However, the function will have to end up doing something different dependent on which button was clicked.
  If, previously, in AS2, I would have added the code on the buttons themselves with methods we (release) (see the SAMPLE CODE 1)
  
  Thus, each button calls the function efficiently navigate and transmits a different image to the function tag.
  Now, I try to recreate this feature in AS3. As you know, it (release) has been abolished (still do not know why), but we must now use event handlers, so I'll try to find a way to pass a different image to the function label argument to navigate. Currently, I can achieve that by using a switch statement to test which button has been clicked and act accordingly (see the SAMPLE CODE 2).
  
  In this simplistic example, this works very well, but in the real world, I have more than 2 buttons and the function navigate would probably much more complicated...
  So I would be able to pass an argument (as in the AS2 example) to the function to navigate... maybe in the addEventListener() method? I tried, but got compile errors (see the EXAMPLE CODE 3):
  
  The issue of the $ 1 Million:
  Is it possible to pass/change dynamically an argument to a function that is triggered by an event listener? (Or is the event that triggered the function the only argument you have?)
  If this is not possible, I would like to hear how you people it would handle (other than to have a switch with 12 cases in there)?

  I found a few solutions that I'll post below for prosperity...

  You can create a dictionary indexed by the targets of future events and store information in there you want to associate with them. Then the Navigate function check that the dictionary to get its parameters:

  Code.
  Button1.addEventListener (MouseEvent.CLICK, navigate, false, 0, true);
  Button2.addEventListener (MouseEvent.CLICK, navigate, false, 0, true);

  var buttonArgs:Dictionary = new Dictionary();
  buttonArgs [Button1] = "FrameLabel1";
  buttonArgs [Button2] = "FrameLabel2";

  function Navigate(e:MouseEvent):void {}
  gotoAndStop (buttonArgs [e.target]);
  }

  This to me, is about the same amount of work than writing a long, but a bit more elegant switch statement, I guess.

  I had a little trouble understanding the following solution, because I did not quite understand important information about event listeners. The addEventListener () method requires a function as the 2nd argument passed to it.
  It didn't quite click on until someone reminded me: Navigate is a function... Navigate("FrameLabel1") is a callfunction...

  So by writing simply navigate, I'm not actually calling the function when calling the addEventListener method, I'm just providing the event with a reference the name listener. Then, when the listener is triggered, the listener will call (and pass a MouseEvent argument to) navigate the function.

  Conversely, by writing Navigate("FrameLabel1") as 2nd argument, the event listener trys to run the function navigate both the addEventListener method is instantiated. And, since then, in this example, the function navigate returned as ": Sub" a compilation error would occur because as I said, an event listener requires a function as 2nd argument data type. This would be essentially as written addEventListener (MouseEvent.Click, Sub, false, 0, true)
  However, there is a way to get around this... basically, instead of setting the function navigate as returning an empty data type, you define a function to return data type and then nest another function (which actually contains the actions you want to run) on the inside.

  Button1.addEventListener (MouseEvent.CLICK, Navigate ("FrameLabel1"), false, 0, true);
  Button2.addEventListener (MouseEvent.CLICK, Navigate ("FrameLabel2"), false, 0, true);

  function Navigate(myLabel:String):Function {}
  return function(evt:MouseEvent):void {}
  gotoAndStop (myLabel);
  }
  }

• 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

  Hello

  It's his practice use? :

  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,

• Passage of the Arguments to the Planner channels

  Comrades of the Oracle,
  
  can I pass arguments to programs in a string?
  
  What works already call a program a job, passing an argument to the program. So far so good.

  Now, when I create a line work, I can not add an argument value more with

  because this will raise an ora-27475.
  Looking at the docs that it seems as if there is no way to do what I want - which I thought I could take for granted...
  Any ideas, anyone?

  a variable binding in a VO should be exposed as an executeWithParams operation in the pageDef file. Just add a new link to the action in the file pageDef (context menu) and select the operation of executeWithParams on the VO. Then, in the field of the argument, reference the bean managed for the value property

• Passing arguments to the script

  Hello

  I have created a dialog box load the files in the folder and when I click the button I run another script of command StartScript (...)

  How can I pass arguments to the script (the paths of files)?

  Thank you

  Hey OzShimon,

  As long as you use a tiara predefined global variables (T1, T2,...)  you'd be fine. You can also define user variables (.) SAV files) or even to declare your own global variables with: call GlobalDim ("Myname").

  These variables are not re-initialized until you restart the script engine. So just change 'obj' for T1 your test should work

  ' Dim obj

  Void Button1_EventClick (ByRef This)

  T1 = "Hello World".

  Call ScriptStart("C:\Users\Oz\Desktop\test.vbs")

  End Sub

  * the script code (test.vbs):

  Call MsgBox (T1)

  Kind regards

• How to pass arguments to the SQL Script in command prompt

  I don't know about the ' & nom_de_variable "to request a value in the command line.
  
  But, how can I pass arguments from the command line for the following script to the command - prompt
  
  Example:
  
  ex_proc. SQL
  
  CREATE OR REPLACE PROCEDURE ex_proc (employee_id NUMBE IN)

  Appellant for procedure above:
  
  BEGIN
  
  ex_proc (100); -The employee id is 100.
  
  END;

  Here are the General controls that we use to run the scripts above-

• How to call a method of the AM with parameters of Bean managed?

  Hello world
  
  I have a situation where I need to call the Managed bean (setDefaultSubInv) AM, under value changes Listner method. Here's what I do, I added the AM method on page links, and then at the bean call it
  
  Class [] paramTypes = {};
  Object [] params = {};
  invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
  
  It works and be able to call this method, if there are no parameters. Say that I pass a parameter to setDefaultSubInv(String a) method AM, I tried to call it bean but raise an error
  
  The string available = 'test ';
  Class [] paramTypes = {String.class};
  Object [] params = {DISP};
  invokeEL ("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
  
  I'm not sure this is the right way to call the method with parameters. Can anyone tell how to call a method of the AM with bean to manage settings
  
  Thank you
  San.

  Just do the following

  1. your method in the Client Interface.
  2 - Add to Page Def.
  3 - Customize your Script like below one to reach your goal.

  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
  operationBinding.getParamsMap () .put ("username", "oracle");
  operationBinding.getParamsMap () .put ("role", "F1211");
  operationBinding.getParamsMap () .put ("Connection", "JDBC");
  Object result = operationBinding.execute ();
  If (! operationBinding.getErrors () .isEmpty ()) {}
  Returns a null value.
  }
  Returns a null value.
  }

  I hope it helps you
  Thank you

• First crash of HP program running with arguments in the RPN

  (The first HP 20150427 firmware version)

  The following basic program will result in the application crash and HP first reboot when running in RPN mode. When executing, it calls for the parameters and then crashes when you press OK to continue execution of the program.

  If I switch to the entry of MANUAL it works very well, however I used to be a fan of RPN so by default, I'm in RPN mode.

  If I put two arguments on the stack and calls the program with CRASH (2) popping the arguments, it works very well.

  EXPORT CRASH (T, P)

  BEGIN

  PRINT (T);

  PRINT (P);

  END;

  Investigation on a bit further, the following program always works, regardless of the input mode:

  EXPORT WORKS()

  BEGIN

  T LOCAL, P;

  INPUT (T);

  INPUT (P);

  PRINT (T);

  PRINT (P);

  END;

  The problem is therefore a very bad error handling in running HP PPL, in the case of a stack overflow. In my view, that it is a BUG in the firmware; rather than crashing and restarting the first HP, it goes down gracefully with a "stack overflow" error

  How can I create an official bug for this problem report?

  This issue seems to be fixed in version 2015 6 17 (8151). I can't reproduce the error.
