- Interface Summary
  Interface | Description
  --- | ---
  CallStack | Strategy for obtaining and printing the current call stack.
  DefaultPooledObjectInfoMBean | The interface that defines the information about pooled objects that will be exposed via JMX.
  EvictionPolicy<T> | To provide a custom eviction policy (i.e.
  GenericKeyedObjectPoolMXBean<K> | Defines the methods that will be made available via JMX.
  GenericObjectPoolMXBean | Defines the methods that will be made available via JMX.

- Class Summary
  Class | Description
  --- | ---
  AbandonedConfig | Configuration settings for abandoned object removal.
  BaseGenericObjectPool<T> | Base class that provides common functionality for `GenericObjectPool` and `GenericKeyedObjectPool`.
  BaseObjectPoolConfig<T> | Provides the implementation for the common attributes shared by the sub-classes.
  CallStackUtils | Utility methods for `CallStack`.
  DefaultEvictionPolicy<T> | Provides the default implementation of `EvictionPolicy` used by the pools.
  DefaultPooledObject<T> | This wrapper is used to track the additional information, such as state, for the pooled objects.
  DefaultPooledObjectInfo | Implementation of object that is used to provide information on pooled objects via JMX.
  EvictionConfig | This class is used by pool implementations to pass configuration information to `EvictionPolicy` instances.
  GenericKeyedObjectPool<K,T> | A configurable `KeyedObjectPool` implementation.
  GenericKeyedObjectPoolConfig<T> | A simple "struct" encapsulating the configuration for a `GenericKeyedObjectPool`.
  GenericObjectPool<T> | A configurable `ObjectPool` implementation.
  GenericObjectPoolConfig<T> | A simple "struct" encapsulating the configuration for a `GenericObjectPool`.
  NoOpCallStack | CallStack strategy using no-op implementations of all functionality.
  PooledSoftReference<T> | Extension of `DefaultPooledObject` to wrap pooled soft references.
  SecurityManagerCallStack | A `CallStack` strategy using a `SecurityManager`.
  SoftReferenceObjectPool<T> | A `SoftReference` based `ObjectPool`.
  ThrowableCallStack | CallStack strategy that uses the stack trace from a `Throwable`.

## Package org.apache.commons.pool2.impl Description

Object pooling API implementations.

`GenericObjectPool` (`GenericKeyedObjectPool`) provides a more robust (but also more complicated) implementation of `ObjectPool` (`KeyedObjectPool`).

`SoftReferenceObjectPool` provides a `SoftReference` based `ObjectPool`.
