Method Detail

name

String name()

Field name

fieldType

IndexableFieldType fieldType()

IndexableFieldType describing the properties of this field.

boost

float boost()

Field boost (you must pre-multiply in any doc boost).

binaryValue

BytesRef binaryValue()

Non-null if this field has a binary value

stringValue

String stringValue()

Non-null if this field has a string value

readerValue

Reader readerValue()

Non-null if this field has a Reader value

numericValue

Number numericValue()

Non-null if this field has a numeric value

tokenStream

TokenStream tokenStream(Analyzer analyzer)
                        throws IOException

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

Parameters:

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

Returns:

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

Throws:

IOException - Can be thrown while creating the TokenStream
