Method Detail

getOrd

public int getOrd(int docID)

Description copied from class: SortedDocValues

Returns the ordinal for the specified docID.

Specified by:

getOrd in class SortedDocValues

Parameters:

docID - document ID to lookup

Returns:

ordinal for the document: this is dense, starts at 0, then increments by 1 for the next value in sorted order. Note that missing values are indicated by -1.

lookupOrd

public BytesRef lookupOrd(int ord)

Description copied from class: SortedDocValues

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

Specified by:

lookupOrd in class SortedDocValues

Parameters:

ord - ordinal to lookup (must be >= 0 and < SortedDocValues.getValueCount())

See Also:

SortedDocValues.getOrd(int)

getValueCount

public int getValueCount()

Description copied from class: SortedDocValues

Returns the number of unique values.

Specified by:

getValueCount in class SortedDocValues

Returns:

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

get

public BytesRef get(int docID)

Description copied from class: BinaryDocValues

Lookup the value for document. The returned BytesRef may be re-used across calls to BinaryDocValues.get(int) so make sure to copy it if you want to keep it around.

Overrides:

get in class SortedDocValues

lookupTerm

public int lookupTerm(BytesRef key)

Description copied from class: SortedDocValues

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

Overrides:

lookupTerm in class SortedDocValues

Parameters:

key - Key to look up
