tokenStream

public TokenStream tokenStream(Analyzer analyzer,
                               TokenStream reuse)

Description copied from interface: IndexableField

Creates the TokenStream used for indexing this field. If appropriate, implementations should use the given Analyzer to create the TokenStreams.

Specified by:

tokenStream in interface IndexableField

Parameters:

analyzer - Analyzer that should be used to create the TokenStreams from

reuse - TokenStream for a previous instance of this field name. This allows custom field types (like StringField and NumericField) that do not use the analyzer to still have good performance. Note: the passed-in type may be inappropriate, for example if you mix up different types of Fields for the same field name. So it's the responsibility of the implementation to check.

Returns:

TokenStream value for indexing the document. Should always return a non-null value if the field is to be indexed
