Description

Interface Summary
MultiTermAwareComponent: Add to any analysis factory component to allow returning an analysis component factory for use with partial terms in prefix queries, wildcard queries, range query endpoints, regex queries, etc.
ResourceLoader: Abstraction for loading resources (streams, files, and classes).
ResourceLoaderAware: Interface for a component that needs to be initialized by an implementation of `ResourceLoader`.

Class Summary
AbstractAnalysisFactory: Abstract parent class for analysis factories `TokenizerFactory`, `TokenFilterFactory` and `CharFilterFactory`.
CharacterUtils: `CharacterUtils` provides a unified interface to Character-related operations to implement backwards compatible character operations based on a `Version` instance.
CharacterUtils.CharacterBuffer: A simple IO buffer to use with `CharacterUtils.fill(CharacterBuffer, Reader)`.
CharArrayIterator: A CharacterIterator used internally for use with `BreakIterator`
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.
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.
FilteringTokenFilter: Abstract base class for TokenFilters that may remove tokens.
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.
StemmerUtil: Some commonly-used stemming functions
StopwordAnalyzerBase: Base class for Analyzers that need to make use of stopword sets.
TokenFilterFactory: Abstract parent class for analysis factories that create `TokenFilter` instances.
TokenizerFactory: Abstract parent class for analysis factories that create `Tokenizer` instances.
WordlistLoader: Loader for text files that represent a list of stopwords.
