Overview of the org.apache.commons.pool2 component
Generic Object pooling API with several implementations.
The org.apache.commons.pool2 package defines a simple
interface for a pool of object instances, and a handful of base
classes that may be useful when creating pool implementations.
The API supports pooling of unique objects which can be requested
via a key as well as pools where all objects are equivalent.
The org.apache.commons.pool2.impl package contains
several pool implementations.
{@link org.apache.commons.pool2.impl.GenericObjectPool
GenericObjectPool} has many configuration options and can support
a limited set of objects such as would be useful in a database
connection pool.
{@link org.apache.commons.pool2.impl.SoftReferenceObjectPool
SoftReferenceObjectPool} has no limit on the number of objects in the
pool, but the garbage collector can remove idle objects from the pool
as needed. There is also a keyed version of
{@link org.apache.commons.pool2.impl.GenericObjectPool
GenericObjectPool},
{@link org.apache.commons.pool2.impl.GenericKeyedObjectPool
GenericKeyedObjectPool}
