abstract TokenStream TokenStream (String fieldName, System.IO.TextReader reader)
 Creates a TokenStream which tokenizes all the text in the provided Reader. Must be able to handle null field name for backward compatibility.
virtual TokenStream ReusableTokenStream (String fieldName, System.IO.TextReader 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.
virtual int GetPositionIncrementGap (String fieldName)
 Invoked before indexing a Fieldable instance if terms have already been added to that field. This allows custom analyzers to place an automatic position increment gap between Fieldable instances using the same field name. The default value position increment gap is 0. With a 0 position increment gap and the typical default token position increment of 1, all terms in a field, including across Fieldable instances, are in successive positions, allowing exact PhraseQuery matches, for instance, across Fieldable instance boundaries.
virtual int GetOffsetGap (IFieldable field)
 Just like GetPositionIncrementGap, except for Token offsets instead. By default this returns 1 for tokenized fields and, as if the fields were joined with an extra space character, and 0 for un-tokenized fields. This method is only called if the field produced at least one token for indexing.
void Close ()
 Frees persistent resources used by this Analyzer
virtual void Dispose ()
