All known Subclasses: org.jacorb.notification.util.AbstractPoolablePool,
| AbstractObjectPool | | abstract public class AbstractObjectPool implements Runnable,Configurable(Code) | | Abstract Base Class for Simple Pooling Mechanism. Subclasses must at least implement the method
newInstance. To use a Object call lendObject. After use the Object must be returned with
returnObject(Object). An Object must not be used after it has been returned to its pool!
This class needs a two phase initialization: configure MUST be invoked before an instance can be used.
