Class LegacySortedSetDocValues

java.lang.Object

org.apache.lucene.codecs.memory.LegacySortedSetDocValues

@Deprecated
abstract class LegacySortedSetDocValues
extends java.lang.Object

Deprecated.

Use SortedSetDocValues instead.

A per-document set of presorted byte[] values.

Per-Document values in a SortedDocValues are deduplicated, dereferenced, and sorted into a dictionary of unique values. A pointer to the dictionary value (ordinal) can be retrieved for each document. Ordinals are dense and in increasing sorted order.

Field Summary

Fields

Modifier and Type	Field	Description
static long	NO_MORE_ORDS	Deprecated. When returned by nextOrd() it means there are no more ordinals for the document.

Constructor Summary

Constructors

Modifier	Constructor	Description
protected	LegacySortedSetDocValues()	Deprecated. Sole constructor.

Method Summary

Modifier and Type	Method	Description
abstract long	getValueCount()	Deprecated. Returns the number of unique values.
abstract BytesRef	lookupOrd(long ord)	Deprecated. Retrieves the value for the specified ordinal.
long	lookupTerm(BytesRef key)	Deprecated. If key exists, returns its ordinal, else returns -insertionPoint-1, like Arrays.binarySearch.
abstract long	nextOrd()	Deprecated. Returns the next ordinal for the current document (previously set by setDocument(int).
abstract void	setDocument(int docID)	Deprecated. Sets iteration to the specified docID

public static final long NO_MORE_ORDS

Deprecated.

When returned by nextOrd() it means there are no more ordinals for the document.

Constructor Detail

LegacySortedSetDocValues

protected LegacySortedSetDocValues()

Deprecated.

Sole constructor. (For invocation by subclass constructors, typically implicit.)

Method Detail

nextOrd

public abstract long nextOrd()

Deprecated.

Returns the next ordinal for the current document (previously set by setDocument(int).

Returns:

next ordinal for the document, or NO_MORE_ORDS. ordinals are dense, start at 0, then increment by 1 for the next value in sorted order.

setDocument

public abstract void setDocument(int docID)

Deprecated.

Sets iteration to the specified docID

Parameters:

docID - document ID

lookupOrd

public abstract BytesRef lookupOrd(long ord)

Deprecated.

Retrieves the value for the specified ordinal. The returned BytesRef may be re-used across calls to lookupOrd so make sure to copy it if you want to keep it around.

Parameters:

ord - ordinal to lookup

See Also:

nextOrd()

getValueCount

public abstract long getValueCount()

Deprecated.

Returns the number of unique values.

Returns:

number of unique values in this SortedDocValues. This is also equivalent to one plus the maximum ordinal.

lookupTerm

public long lookupTerm(BytesRef key)

Deprecated.

If key exists, returns its ordinal, else returns -insertionPoint-1, like Arrays.binarySearch.

Parameters:

key - Key to look up

termsEnum

public TermsEnum termsEnum()
                    throws java.io.IOException

Deprecated.

Returns a TermsEnum over the values. The enum supports TermsEnum.ord() and TermsEnum.seekExact(long).

Throws:

java.io.IOException
