Class HindiNormalizationFilter

A Lucene.Net.Analysis.TokenFilter that applies HindiNormalizer to normalize the orthography.

In some cases the normalization may cause unrelated terms to conflate, so to prevent terms from being normalized use an instance of SetKeywordMarkerFilter or a custom Lucene.Net.Analysis.TokenFilter that sets the Lucene.Net.Analysis.TokenAttributes.IKeywordAttribute before this Lucene.Net.Analysis.TokenStream.

A Lucene.Net.Analysis.TokenFilter that applies HindiNormalizer to normalize the orthography.

In some cases the normalization may cause unrelated terms to conflate, so to prevent terms from being normalized use an instance of SetKeywordMarkerFilter or a custom Lucene.Net.Analysis.TokenFilter that sets the Lucene.Net.Analysis.TokenAttributes.IKeywordAttribute before this Lucene.Net.Analysis.TokenStream.

Methods

IncrementToken()

Consumers (i.e., Lucene.Net.Index.IndexWriter) use this method to advance the stream to the next token. Implementing classes must implement this method and update the appropriate Lucene.Net.Util.IAttributes with the attributes of the next token.

The producer must make no assumptions about the attributes after the method has been returned: the caller may arbitrarily change it. If the producer needs to preserve the state for subsequent calls, it can use Lucene.Net.Util.AttributeSource.CaptureState() to create a copy of the current attribute state.

this method is called for every token of a document, so an efficient implementation is crucial for good performance. To avoid calls to Lucene.Net.Util.AttributeSource.AddAttribute<T>() and Lucene.Net.Util.AttributeSource.GetAttribute<T>(), references to all Lucene.Net.Util.IAttributes that this stream uses should be retrieved during instantiation.

To ensure that filters and consumers know which attributes are available, the attributes must be added during instantiation. Filters and consumers are not required to check for availability of attributes in Lucene.Net.Analysis.TokenStream.IncrementToken().

Declaration

public override bool IncrementToken()

Returns

Type	Description
bool	false for end of stream; true otherwise
