Method Detail

getNumeric

public NumericDocValues getNumeric(FieldInfo fieldInfo)
                            throws java.io.IOException

Description copied from class: DocValuesProducer

Returns NumericDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread. The behavior is undefined if the doc values type of the given field is not DocValuesType.NUMERIC. The return value is never null.

Specified by:

getNumeric in class DocValuesProducer

Throws:

java.io.IOException

getNumericNonIterator

java.util.function.IntFunction<java.lang.Long> getNumericNonIterator(FieldInfo fieldInfo)
                                                              throws java.io.IOException

Throws:

java.io.IOException

getNumericDocsWithField

private SimpleTextDocValuesReader.DocValuesIterator getNumericDocsWithField(FieldInfo fieldInfo)

Throws:

java.io.IOException

getBinary

public BinaryDocValues getBinary(FieldInfo fieldInfo)
                          throws java.io.IOException

Description copied from class: DocValuesProducer

Returns BinaryDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread. The behavior is undefined if the doc values type of the given field is not DocValuesType.BINARY. The return value is never null.

Specified by:

getBinary in class DocValuesProducer

Throws:

java.io.IOException

getBinaryDocsWithField

private SimpleTextDocValuesReader.DocValuesIterator getBinaryDocsWithField(FieldInfo fieldInfo)
