java.lang.Object
org.apache.xml.security.utils.WeakObjectPool<T,E>
Deprecated.
This class is no longer in use in Santuario 2.1.4
Abstract base class for pooling objects. The two public methods are
getObject() and (repool(Object). Objects are held through
weak references so even objects that are not repooled are subject to garbage collection.
Subclasses must implement the abstract createObject().
Internally, the pool is stored in a java.util.concurrent.LinkedBlockingDeque instance.
