Class Summary

Class	Description
Analyzer	An Analyzer builds TokenStreams, which analyze text.
Analyzer.ReuseStrategy	Strategy defining how TokenStreamComponents are reused per call to Analyzer.tokenStream(String, java.io.Reader).
Analyzer.TokenStreamComponents	This class encapsulates the outer components of a token stream.
AnalyzerWrapper	Extension to Analyzer suitable for Analyzers which wrap other Analyzers.
CachingTokenFilter	This class can be used if the token attributes of a TokenStream are intended to be consumed more than once.
CharacterUtils	Utility class to write tokenizers or token filters.
CharacterUtils.CharacterBuffer	A simple IO buffer to use with CharacterUtils.fill(CharacterBuffer, Reader).
CharArrayMap<V>	A simple class that stores key Strings as char[]'s in a hash table.
CharArraySet	A simple class that stores Strings as char[]'s in a hash table.
CharFilter	Subclasses of CharFilter can be chained to filter a Reader They can be used as Reader with additional offset correction.
DelegatingAnalyzerWrapper	An analyzer wrapper, that doesn't allow to wrap components or readers.
FilteringTokenFilter	Abstract base class for TokenFilters that may remove tokens.
GraphTokenFilter	An abstract TokenFilter that exposes its input stream as a graph Call GraphTokenFilter.incrementBaseToken() to move the root of the graph to the next position in the TokenStream, GraphTokenFilter.incrementGraphToken() to move along the current graph, and GraphTokenFilter.incrementGraph() to reset to the next graph based at the current root.
LowerCaseFilter	Normalizes token text to lower case.
StopFilter	Removes stop words from a token stream.
StopwordAnalyzerBase	Base class for Analyzers that need to make use of stopword sets.
TokenFilter	A TokenFilter is a TokenStream whose input is another TokenStream.
Tokenizer	A Tokenizer is a TokenStream whose input is a Reader.
TokenStream	A TokenStream enumerates the sequence of tokens, either from Fields of a Document or from query text.
TokenStreamToAutomaton	Consumes a TokenStream and creates an Automaton where the transition labels are UTF8 bytes (or Unicode code points if unicodeArcs is true) from the TermToBytesRefAttribute.
WordlistLoader	Loader for text files that represent a list of stopwords.
