Method Details

getNumeric

public NumericDocValues getNumeric(FieldInfo field)
                            throws 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:

IOException

getBinary

public BinaryDocValues getBinary(FieldInfo field)
                          throws 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:

IOException

getSorted

public SortedDocValues getSorted(FieldInfo field)
                          throws IOException

Description copied from class: DocValuesProducer

Returns SortedDocValues 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.SORTED. The return value is never null.

Specified by:

getSorted in class DocValuesProducer

Throws:

IOException

getSortedNumeric

public SortedNumericDocValues getSortedNumeric(FieldInfo field)
                                        throws IOException

Description copied from class: DocValuesProducer

Returns SortedNumericDocValues 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.SORTED_NUMERIC. The return value is never null.

Specified by:

getSortedNumeric in class DocValuesProducer

Throws:

IOException

getSortedSet

public SortedSetDocValues getSortedSet(FieldInfo field)
                                throws IOException

Description copied from class: DocValuesProducer

Returns SortedSetDocValues 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.SORTED_SET. The return value is never null.

Specified by:

getSortedSet in class DocValuesProducer

Throws:

Throws:

IOException

checkIntegrity

public void checkIntegrity()
                    throws IOException

Description copied from class: DocValuesProducer

Checks consistency of this producer

Note that this may be costly in terms of I/O, e.g. may involve computing a checksum value against large data files.

Specified by:

checkIntegrity in class DocValuesProducer

Throws:

IOException

getMergeInstance

public DocValuesProducer getMergeInstance()

Description copied from class: DocValuesProducer

Returns an instance optimized for merging. This instance may only be consumed in the thread that called DocValuesProducer.getMergeInstance().

The default implementation returns this

Overrides:

getMergeInstance in class DocValuesProducer

toString

public String toString()

Overrides:

toString in class Object
