C# Class Lucene.Net.Analysis.Miscellaneous.LimitTokenPositionFilter

This TokenFilter limits its emitted tokens to those with positions that are not greater than the configured limit.

By default, this filter ignores any tokens in the wrapped {@code TokenStream} once the limit has been exceeded, which can result in {@code reset()} being called prior to {@code incrementToken()} returning {@code false}. For most {@code TokenStream} implementations this should be acceptable, and faster then consuming the full stream. If you are wrapping a {@code TokenStream} which requires that the full stream of tokens be exhausted in order to function properly, use the #LimitTokenPositionFilter(TokenStream,int,boolean) consumeAllTokens option.

Public Methods

Method Description
IncrementToken ( ) : bool
LimitTokenPositionFilter ( TokenStream @in, int maxTokenPosition ) : Lucene.Net.Analysis.Tokenattributes

Build a filter that only accepts tokens up to and including the given maximum position. This filter will not consume any tokens with position greater than the maxTokenPosition limit.
LimitTokenPositionFilter ( TokenStream @in, int maxTokenPosition, bool consumeAllTokens ) : Lucene.Net.Analysis.Tokenattributes

Build a filter that limits the maximum position of tokens to emit.
Reset ( ) : void
