Inherited Methods

From class org.apache.lucene.analysis.Analyzer

void	close() Frees persistent resources used by this Analyzer
int	getOffsetGap(Fieldable field) Just like `getPositionIncrementGap(String)`, except for Token offsets instead.
int	getPositionIncrementGap(String fieldName) Invoked before indexing a Fieldable instance if terms have already been added to that field.
Object	getPreviousTokenStream() Used by Analyzers that implement reusableTokenStream to retrieve previously saved TokenStreams for re-use by the same thread.
TokenStream	reusableTokenStream(String fieldName, Reader reader) Creates a TokenStream that is allowed to be re-used from the previous time that the same thread called this method.
void	setOverridesTokenStreamMethod(Class<? extends Analyzer> baseClass) This method is deprecated. This is only present to preserve back-compat of classes that subclass a core analyzer and override tokenStream but not reusableTokenStream
void	setPreviousTokenStream(Object obj) Used by Analyzers that implement reusableTokenStream to save a TokenStream for later re-use by the same thread.
abstract TokenStream	tokenStream(String fieldName, Reader reader) Creates a TokenStream which tokenizes all the text in the provided Reader.

Public Methods

public TokenStream reusableTokenStream (String fieldName, Reader reader)

Creates a TokenStream that is allowed to be re-used from the previous time that the same thread called this method. Callers that do not need to use more than one TokenStream at the same time from this analyzer should use this method for better performance.

Throws

IOException

public TokenStream tokenStream (String fieldName, Reader reader)

Creates a TokenStream which tokenizes all the text in the provided Reader. Must be able to handle null field name for backward compatibility.
