| StackKeyedObjectPool | | public class StackKeyedObjectPool extends BaseKeyedObjectPool implements KeyedObjectPool(Code) | | A simple,
java.util.Stack Stack -based
KeyedObjectPool implementation.
Given a
KeyedPoolableObjectFactory , this class will maintain
a simple pool of instances. A finite number of "sleeping"
or inactive instances is enforced, but when the pool is
empty, new instances are created to support the new load.
Hence this class places no limit on the number of "active"
instances created by the pool, but is quite useful for
re-using Objects without introducing
artificial limits.

max - cap on the number of "sleeping" instances in the pool |
| StackKeyedObjectPool | | public StackKeyedObjectPool(KeyedPoolableObjectFactory factory, int max, int init)(Code) | | Create a new SimpleKeyedObjectPool using
the specified factory to create new instances.
capping the number of "sleeping" instances to max,
and initially allocating a container capable of containing
at least init instances.

factory - the KeyedPoolableObjectFactory used to populate the pool
Parameters:
max - cap on the number of "sleeping" instances in the pool
Parameters:
init - initial size of the pool (this specifies the size of the container,it does not cause the pool to be pre-populated.) |
