Method Summary

void	destroy(T t) is invoked on every instance when it is being "dropped" from the pool (whether due to the response from validateObject, or for reasons specific to the pool implementation.)
void	passivate(T t) is invoked on every instance when it is returned to the pool.
boolean	validate(T t) is invoked on activated instances to make sure they can be borrowed from the pool. validateObject may also be used to test an instance being returned to the pool before it is passivated.
