Class SimplePoolPassive

java.lang.Object
  org.activemath.omdocjdom.SimplePool
      org.activemath.omdocjdom.SimplePoolPassive

public class SimplePoolPassive
extends SimplePool

This extension of SimplePool is meant for SimplePoolPassive.Wrapper objects that do not SimplePool.Poolable.run() but are notified of their SimplePool.Poolable.isBusy() status using method-calls from outside.

The pool is created with a (fixed) array of wrapped objects. A free one is then obtained using getAFreeOne(int, int) who's SimplePoolPassive.Wrapper.setBusy(boolean) has to be called (with true). Once finished the SimplePoolPassive.Wrapper.setBusy(boolean)(false) is then to be called, freeing the object for a next call to getAFreeOne(int, int).

Please note that this class and its parent class will probably undergo deep changes so it should be used at few places.
