All Implemented Interfaces:

Disposable, Initializable, LogEnabled, Pool, Resizable, ThreadSafe

Deprecated. DefaultComponentPool is no longer used by the PoolableComponentHandler.

public class DefaultComponentPool

extends SoftResourceLimitingPool

implements Initializable

This is the implementation of Pool for Avalon Components that is thread safe. For Component Management, we need soft resource limiting due to the possibility of spikes in demand. This pool will destroy all unnecessary Components when they are no longer needed.
