• How to access the static class variable calendar / singleton?

  How can I access a timeline of a static class variable / singleton?

  You can pass any object to display list to your class when instantiating it.  all objects in the display list has a placement property that allows access to the stage and them you can use the correct path/name to your variable.

• error of static class

  I have a static class:

  package VO
  {
  public class ArrayValues
  {
  private static var instance: ArrayValues = new ArrayValues();
  
  nominal values will replace the first with English-language versions
  If the user clicks on "Spanish" they will be replaced with
  private var yesNoArray:Array = new Array('1','2');
  private var utilityArray:Array = new Array('1','2');
  
  public void ArrayValues()
  {
  error ("ArrayValues is called by its instance");
  }
  
  Public Shared function getInstance (): ArrayValues
  {
  return instance;
  }
  
  public function getYesNoArray (): Array
  {
  Return yesNoArray;
  }
  public void setYesNoArray(input:Array):void
  {
  yesNoArray = entry;
  }
  

  It is invoked here:

  import VOS. ArrayValues;
  import VOS. InputData;
  import VOS. InputLabels;
  
  [Bindable]
  public var saveData:InputData = InputData.getInstance ();
  
  [Bindable]
  168 public var getArrays:ArrayValues = ArrayValues.getInstance ();
  ...

  It generates this error:

  Error: ArrayValues is called by its instance
  to VO::ArrayValues() [C:\FSCalc\Flex\FSCalc\src\VO\ArrayValues.as:14]
  to VO: ArrayValues$ cinit)
  Global $init () [C:\FSCalc\Flex\FSCalc\src\VO\ArrayValues.as:3]

  in FSCalc / _FSCalc_InputForm1_i)
  in FSCalc / _FSCalc_Array6_c)
  ...

  What I am doing wrong?

  PS, it is normal to take almost 10 minutes a) go to your discussions, b) read a reply to a thread and c) come back to the normal discussion?  That seems excessive to me.

  If you try to reach singleton,

  Your manufacture should look like this,

  public void ArrayValues(access:SingletonEnforcer)
  {

  If (access is nothing)
  {
  error ("ArrayValues is called by its instance");
  }

  }

  a variable,

  public static private var _instance: ArrayValues;

  Public Shared function getInstance (): ArrayValues

  {
  If (_instance is nothing)
  {
  _instance = new ArrayValues (new SingletonEnforcer());
  }
  return _instance;

  }

  And another class in the same file,

  class SingletonEnforcer
  {
  }

  If static class functions are removed from the manufacturer and applied to the place inside the body of the constructor, it works without error. Similarly, you can call the constructor with the functions of the static class as parameters, without causing an internal error.

• "new static class qualified."

  Hi all
  
  I have a class of RandomGenerator with a nested public static String class, which extends from CountingGenerator with a nested class public static String, which in turn has a next() method to generate a following string object. Now, how do I actually use, how do I get a reference to the nested class so that I can call the following method. I tried this code, but it throws RuntimeException: code source Uncompilable - qualified new static class:
  

  public class FillTreeSet {
      public static void main(String[] args) {
          RandomGenerator rg = new RandomGenerator();
          RandomGenerator.String rgs = rg.new String();   //throws the exception
      }    
  }

  It's the RandomGenerator class:
  

  public class RandomGenerator {
      public static class String extends CountingGenerator.String {
          { cg = new Character(); }
          public String() {}
          public String(int length) { super(length); }
      }
  }

  And it comes to the CountingGenerator class:
  

  public class CountingGenerator {
      public static class String implements Generator<java.lang.String> {
          private int length = 7;
          Generator<java.lang.Character> cg = new Character();
          public String() {}
          public String(int length) { this.length = length; }
          @Override
          public java.lang.String next() {
              char[] buf = new char[length];
              for (int i = 0; i < length; i++)
                  buf[i] = cg.next();
              return new java.lang.String(buf);
          }
      }
  }

  Thanks in advance.

  Since this is a static inner class, you must specify:

  new RandomGenerator.String();
  

  Your code would work if it were a non-static inner class.

• initializer, instance and static initializer blocks

  Hi guys,.
  
  I have read the foregoing, mentioned in the JLS and also in a book before, but I still do not understand, what is the use of these. I have sort of a rough idea, but not exactly. I mean, what is the purpose of the initializer for instance and static initializer blocks, how can be useful? I understand that I can run pieces of code that initialize instance and static variables accordingly, but what is the difference then to use a constructor to initialize these areas? Are these pieces of code executed before the execution of any manufacturer, or when otherwise?
  
  Sorry for my noob, I learn.
  
  PR.

  Static initializer blocks are executed when the class is loaded, once (a classloader). So that they have some use. Initializers for instance differ a lot of builders (I think that code in the initializers of the instance has been copied to each manufacturer), but they can be useful with anonymous inner classes for example (since you cannot define constructors it (well, you can, but you can't call them)).

  They have a limited use, but it is good to recognize them if you see them.

• Static class to change TextField

  Hello

  I'm doing a static class that will change the text in a TextField inside a SWF file.

  In this case, I have a MovieClip with a TextField with a message inside. I want to be able to make a class that gives this TextField and a message, what will change in the button.

  Certainly that I forget something obvious, I get the correct trace messages, but the textfield object disappears. The original text is 'Start' and I want to change cela 'OK '. For now I just want to change the text, but then I want to be able to change the text format.

  So far, I have this:

  package

  {

  import flash.display.MovieClip;

  SerializableAttribute public class ChangeTextField extends MovieClip

  {

  public void ChangeTextField(_textField:Object,__text:String):void {}

  }

  public static void change(_textField:TextField,__text:String):void {}

  trace ("CHANGETEXTFIELD" + _textField); Return to 'start '.

  _textField.text = _text;

  }

  }

  }

  In another class, I loaded the SWF and its contents is inside a MovieClip so that I can reference it. To edit the text in the TextField I would do something like:

  ChangeTextField.change (okButton.normal.label_tx, "OK");

  trace (okButton.normal.label_tx. (Text); Returns "OK".

  By the messages trace, all that does what it is supposed to do, but the object TextField disappears.

  Any idea?

  See you soon.

  If you see all traces of planned, make sure that your policy is incorporated.

• How to get the jar file without knowing his name and any class on the inside?

  Hello, everyone!
  
  I would like to know if there is a way to get a reference programmatically in the original container without knowing his name and any class it contains. I mean by "initial pot" the pot that was called in the prompt, like this:
  

  java -jar jarfile.jar

  or in another way, in a graphics system. To be honest, what I really want is to get a reference to the manifest of the jar, but I know that if I can get a reference to the jar I can get a reference to its manifest file. Or if you know a way to get the manifest directly, it would also be useful. So, is there a way to do this?
  
  Thank you.
  
  Marcos

  Ah, so you want to find the calling class and get its source code.

  I managed to get the class calling on occasion, but this is probably a somewhat fragile solution. You must extend SecurityManager because getClassContext() is a protected method.

      private static class CallerFetch extends SecurityManager {
  
          public Class getCallerClass() {
              return getClassContext()[3];
          }
      }
      private static CallerFetch callerFetch =
              new CallerFetch();
  
      /**
       * Find the class of the code which called the
       * method that invokes this method.
       * @return The class of the caller's caller
       */
      public static Class getCallerClass() {
          return callerFetch.getCallerClass();
      }
  

• can we create a static class in actionscript 3.0

  Hi Julie,.

  There is not specifically a static class in Flex you can declare it at compile time. However, you can have static variables and methods in your class and you can call them by using the class name itself without creating an instance of this class.

• Static Classes & events

  Can it only an instance of a class expedition event, or the static class can too?

  We have static class MyManager:

  package managers

  {

  Import mx.rpc.CallResponder;

  import of services. MyDataService;

  Import valueObjects.MyValueObject;

  Public NotInheritable class MyManager

  {

  public static var updateDataResult:CallResponder = new CallResponder();

  private static var myDataService:MyDataService = new MyDataService ();

  private static var myValueObject:MyValueObject = new MyValueObject();

  Public Shared function updateMyDataService (): void {}

  updateDataResult.token = myDataService.update (myValueObject);

  }

  }

  }

  And the other class which calls:

  import managers. MyManager;

  MyManager.updateMyDataService ();

  MyManager.updateDataResult.addEventListener (ResultEvent.RESULT, resultReceived);

  and this event listener does not work.

  Hi Banditizm,

  Yes you can even send your static callResponders events, but I think that the difficulty you might face you cannot capture or listen to events sent.

  You can do something, you can send these events w.r.t. systemManager and also listen to these WRT events there.

  I mean your shipment to help call the event as below...

  systemManager.dispatchEvent (new Event ("dataLoadComplete"));

  And you can listen in your mxml or as .as file below...

  systemManager.addEventListener ("dataLoadComplete", onDataLoadComplete);

  Thank you

• IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static

  Hello

  My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:

  "Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)

  NAT takes place before the encryption verification!

  In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?

  Thanks for any help

  Best regards

  Heiko

  Hello

  Try to change your static NAT with static NAT based policy.

  That is to say the static NAT should not be applicable for VPN traffic

• ASA 5500 and static NAT 1-to-1

  We currently have a pair of s ASA 5500 failover providing firewall & nat with inside, outside and the dmz interfaces. We do PAT interface for most of the internal to the external and static connections 1-to-1 NAT for specific hosts that need to accept connections from the outside inside. The space of the static nat is a 27 which includes the address of the external interface. It's that everything is working properly.

  However, we are out of space for the static NAT to this/27. I would like to be able to add a different network, probably another 27, for the more static NAT but I'm a hard time to find the best way to do it. Is this possible with a network that does not include the external interface on the ASA?

  Here are some of our current NAT config:

  Global interface 10 (external)

  NAT (inside) 10 0.0.0.0 0.0.0.0

  (dmz1, outside) static dmz1-net-net dmz1 netmask 255.255.255.224

  static (inside, dmz1) 192.168.0.0 192.168.0.0 netmask 255.255.0.0

• Crackling and static

  I just upgraded my iMac with OS X El Capitan. Now when I change my podcast, recorded in multi tracks, I hear crackling and static. When I export the file to a drive MP3 the problem isn't here. Any suggestions?

  Also, now when I switch back between wavelength and multitrack forms, it takes seconds to change (he used to make the quick switch) and the rotation color wheel appears during the shift.

  The attached note warning appears in a media window and hides. I wonder if it's related.

  You are using an external audio interface or map of its Apple built in?

  In any case, El Capitan, from all reports, was a disaster in terms of audio performance.  If you do not have the latest version of El Capitan, download the upgrade... It fixes some of the audo related issues.  (But, alas, not all.)  It is not just an audition... many DAW and audio hardware companies have issued warnings not to go yet.  Indeed, the last bug fix worked on hearing for most users.

  You can try to increase the latency/Buffer setting in Edition/Preferences/Audio Hardware.  There's a chance that might help.

  In addition, you may need to wait for the next difficulty of Apple bug... or downgrade to the previous version of the operating system.
