Class E4ObjectCounter

java.lang.Object
  e4s.util.E4Object
      e4s.util.E4ObjectCounter

public class E4ObjectCounter
extends E4Object

Counter for instanciated E4Objects. You can turn on or off the object counter here using the #setObjectCounter(boolean method. The object counter tracks the number of Objects (as beeing part of E4S or your E4S application) that are inherited by E4Object. This number will be incremented each time an object is instanciated but decremented when the finalize() operator is called. Please note, that almost all E4S classes are inherited from that E4Object class, by doing so you will get a complete picture of objects created but this also causes an overhead in performance.

setObjectCounter

public static void setObjectCounter(boolean mode,
                                    boolean clear)

Turn the object counter on or off. The object counter tracks the number of Objects (as beeing part of E4S or your E4S application) created by their number. This number will be incremented each time an object is instanciated but decremented when the finalize() operator is called. Please note, that almost all E4S classes are inherited from that E4Object class, by doing so you will get a complete picture of objects created but this also causes an overhead in performance.

Parameters:

mode - true turns on the object count mechanism, false turns it off and deletes all previous stored informations.
