Method Details

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.

lookupOrd

public BytesRef lookupOrd(long ord)
                   throws IOException

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

Throws:

IOException

• SortedSetDocValues.nextOrd()

lookupTerm

public long lookupTerm(BytesRef key)
                throws IOException

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

Throws:

IOException

termsEnum

public TermsEnum termsEnum()
                    throws IOException

Description copied from class: SortedSetDocValues

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

Overrides:

termsEnum in class SortedSetDocValues

Throws:

IOException
