cz.cuni.amis.utils.flag
Class Flag.DoInSync<T>

java.lang.Object
  cz.cuni.amis.utils.flag.Flag.DoInSync<T>

Type Parameters:

T -

Direct Known Subclasses:

FlagInteger.DoInSyncWithReason

Enclosing class:

Flag<T>

public abstract static class Flag.DoInSync<T>
extends java.lang.Object

Usage of this abstract class is as simple as it could be ... all you have to do is to instantiate it (using anonymous objects).

Example:

Flag<Integer> flag = new Flag<Integer>(10);

flag.inSync( new Flag.DoInSync<Integer>(flag) {

public abstract void execute(Integer flagValue) {

setFlag(flagValue+1);

}

} );

No need to do anything else! The class will submit itself to the flag upon construction.

Use it to create correct counters (or use directly FlagInteger class).
