Class Summary

Class	Description
AbstractAnalysisFactory	Abstract parent class for analysis factories TokenizerFactory, TokenFilterFactory and CharFilterFactory.
AnalysisSPILoader<S extends AbstractAnalysisFactory>	Helper class for loading named SPIs from classpath (e.g.
CharArrayIterator	A CharacterIterator used internally for use with BreakIterator
CharFilterFactory	Abstract parent class for analysis factories that create CharFilter instances.
CharTokenizer	An abstract base class for simple, character-oriented tokenizers.
ClasspathResourceLoader	Simple ResourceLoader that uses ClassLoader.getResourceAsStream(String) and Class.forName(String,boolean,ClassLoader) to open resources and classes, respectively.
ElisionFilter	Removes elisions from a TokenStream.
ElisionFilterFactory	Factory for ElisionFilter.
FilesystemResourceLoader	Simple ResourceLoader that opens resource files from the local file system, optionally resolving against a base directory.
OpenStringBuilder	A StringBuilder that allows one to access the array.
RollingCharBuffer	Acts like a forever growing char[] as you read characters into it from the provided reader, but internally it uses a circular buffer to only hold the characters that haven't been freed yet.
SegmentingTokenizerBase	Breaks text into sentences with a BreakIterator and allows subclasses to decompose these sentences into words.
StemmerUtil	Some commonly-used stemming functions
TokenFilterFactory	Abstract parent class for analysis factories that create TokenFilter instances.
TokenizerFactory	Abstract parent class for analysis factories that create Tokenizer instances.
UnicodeProps	This file contains unicode properties used by various CharTokenizers.
