Method Detail

nextOrd

public long nextOrd()

Description copied from class: SortedSetDocValues

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

Specified by:

nextOrd in class SortedSetDocValues

Returns:

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

setDocument

public void setDocument(int docID)

Description copied from class: SortedSetDocValues

Sets iteration to the specified docID

Specified by:

setDocument in class SortedSetDocValues

Parameters:

docID - document ID

lookupOrd

public BytesRef lookupOrd(long ord)

Description copied from class: SortedSetDocValues

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.

Specified by:

lookupOrd in class SortedSetDocValues

Parameters:

ord - ordinal to lookup

See Also:

SortedSetDocValues.nextOrd()

getValueCount

public long getValueCount()

Description copied from class: SortedSetDocValues

Returns the number of unique values.

Specified by:

getValueCount in class SortedSetDocValues

Returns:

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

lookupTerm

public long lookupTerm(BytesRef key)

Description copied from class: SortedSetDocValues

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

Overrides:

lookupTerm in class SortedSetDocValues

Parameters:

key - Key to look up
