ObjectPool
ObjectPool
defines a simple pooling interface.
-
GenericObjectPool:
ObjectPool implementation with configurable LIFO/FIFO behavior.
The default behavior is for the pool to act as a LIFO queue. What this
means is that when there are idle objects available in the pool,
borrowObject returns the most recently returned ("last in") instance.
If the
lifo the property of the pool false, instances are
returned in the opposite order - first-in, first-out.
-
SoftReferenceObjectPool:
ObjectPool implementation with a LIFO (Last In First Out) behavior. Additionally this pool wraps
each object in a SoftReference allowing the garbage collector to remove them in response to
memory demand.
KeyedObjectPool
A KeyedObjectPool
pools instances of multiple types. Each type may be accessed using an arbitrary key.
