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 Comparable<E>>	This class implements the heap interface using a List as the underlying data structure.
MarkableFileInputStreamFactory	A factory that creates MarkableFileInputStream from a File
ObjectStreamUtils
ParagraphStream	Stream filter which merges text lines into paragraphs.
PlainTextByLineStream	Reads a plain text file and return each line as a String object.
ReverseListIterator<T>	An iterator for a list which returns values in the opposite order as the typical list iterator.
Sequence	Represents a weighted sequence of outcomes.
Span	Class for storing start and end integer offsets.
StringList	The StringList is an immutable list of Strings.
StringUtil
TrainingParameters
TreeHeap<E>	Deprecated not used anymore, when there is need for a heap use ListHeap instead
Version	The Version class represents the OpenNlp Tools library version.
