    Class JapaneseBaseFormFilter

    Replaces term text with the IBaseFormAttribute.

    This acts as a lemmatizer for verbs and adjectives. To prevent terms from being stemmed use an instance of Lucene.Net.Analysis.Miscellaneous.SetKeywordMarkerFilter or a custom Lucene.Net.Analysis.TokenFilter that sets the Lucene.Net.Analysis.TokenAttributes.IKeywordAttribute before this Lucene.Net.Analysis.TokenStream.

    JapaneseBaseFormFilter(TokenStream)

    Replaces term text with the IBaseFormAttribute.

    This acts as a lemmatizer for verbs and adjectives. To prevent terms from being stemmed use an instance of Lucene.Net.Analysis.Miscellaneous.SetKeywordMarkerFilter or a custom Lucene.Net.Analysis.TokenFilter that sets the Lucene.Net.Analysis.TokenAttributes.IKeywordAttribute before this Lucene.Net.Analysis.TokenStream.
    Declaration
    public JapaneseBaseFormFilter(TokenStream input)
    Parameters
    Type Name Description
    TokenStream input

    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()

    Type Description
    bool

    false for end of stream; true otherwise
