<?xml version="1.0"?> <doc> <assembly> <name>Lucene.Net</name> </assembly> <members> <member name="T:Lucene.Net.Analysis.Analyzer"> <summary>An Analyzer builds TokenStreams, which analyze text. It thus represents a policy for extracting index terms from text. <p/> Typical implementations first build a Tokenizer, which breaks the stream of characters from the Reader into raw Tokens. One or more TokenFilters may then be applied to the output of the Tokenizer. </summary> </member> <member name="M:Lucene.Net.Analysis.Analyzer.TokenStream(System.String,System.IO.TextReader)"> <summary>Creates a TokenStream which tokenizes all the text in the provided Reader. Must be able to handle null field name for backward compatibility. </summary> </member> <member name="M:Lucene.Net.Analysis.Analyzer.ReusableTokenStream(System.String,System.IO.TextReader)"> <summary>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. </summary> </member> <member name="M:Lucene.Net.Analysis.Analyzer.GetPreviousTokenStream"> <summary>Used by Analyzers that implement reusableTokenStream to retrieve previously saved TokenStreams for re-use by the same thread. </summary> </member> <member name="M:Lucene.Net.Analysis.Analyzer.SetPreviousTokenStream(System.Object)"> <summary>Used by Analyzers that implement reusableTokenStream to save a TokenStream for later re-use by the same thread. </summary> </member> <member name="M:Lucene.Net.Analysis.Analyzer.SetOverridesTokenStreamMethod(System.Type)"> <deprecated> This is only present to preserve back-compat of classes that subclass a core analyzer and override tokenStream but not reusableTokenStream </deprecated> </member> <member name="M:Lucene.Net.Analysis.Analyzer.GetPositionIncrementGap(System.String)"> <summary> 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. </summary> <param name="fieldName">Fieldable name being indexed. </param> <returns> position increment gap, added to the next token emitted from <see cref="M:Lucene.Net.Analysis.Analyzer.TokenStream(System.String,System.IO.TextReader)"/> </returns> </member> <member name="M:Lucene.Net.Analysis.Analyzer.GetOffsetGap(Lucene.Net.Documents.Fieldable)"> <summary> Just like <see cref="M:Lucene.Net.Analysis.Analyzer.GetPositionIncrementGap(System.String)"/>, 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. </summary> <param name="field">the field just indexed </param> <returns> offset gap, added to the next token emitted from <see cref="M:Lucene.Net.Analysis.Analyzer.TokenStream(System.String,System.IO.TextReader)"/> </returns> </member> <member name="M:Lucene.Net.Analysis.Analyzer.Close"> <summary>Frees persistent resources used by this Analyzer </summary> </member> <member name="T:Lucene.Net.Analysis.ASCIIFoldingFilter"> <summary> This class converts alphabetic, numeric, and symbolic Unicode characters which are not in the first 127 ASCII characters (the "Basic Latin" Unicode block) into their ASCII equivalents, if one exists.
