Method Details

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.

lookupOrd

public BytesRef lookupOrd(int ord)
                   throws IOException

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())

Throws:

IOException

• SortedDocValues.ordValue()

lookupTerm

public int lookupTerm(BytesRef key)
               throws IOException

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

Throws:

IOException

termsEnum

public TermsEnum termsEnum()
                    throws IOException

Description copied from class: SortedDocValues

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

Overrides:

termsEnum in class SortedDocValues

Throws:

IOException
