Class Summary

Class	Description
AbstractEventStream<T>
AbstractObjectStream<T>
BaseToolFactory	Base class for all tool factories.
BeamSearch<T>	Performs k-best search over sequence.
Cache	Provides fixed size, pre-allocated, least recently used replacement cache.
CollectionObjectStream<E>
CountedSet<E>	Set which counts the number of times a values are added to it.
EventTraceStream
FilterObjectStream<S,T>	Abstract base class for filtering ObjectStreams.
HashList	Class which creates mapping between keys and a list of values.
ListHeap<E extends java.lang.Comparable<E>>	This class implements the heap interface using a List as the underlying data structure.
