Method Detail

nextValue

public double nextValue()
                 throws IOException

Description copied from class: SortedNumericDoubleDocValues

Iterates to the next value in the current document. Do not call this more than SortedNumericDoubleDocValues.docValueCount() times for the document.

Specified by:

nextValue in class SortedNumericDoubleDocValues

Returns:

next value

Throws:

IOException

docValueCount

public int docValueCount()

Description copied from class: SortedNumericDoubleDocValues

Retrieves the number of values for the current document. This must always be greater than zero. It is illegal to call this method after SortedNumericDoubleDocValues.advanceExact(int) returned false.

Specified by:

docValueCount in class SortedNumericDoubleDocValues

Returns:

value count

advanceExact

public boolean advanceExact(int doc)
                     throws IOException

Description copied from class: SortedNumericDoubleDocValues

Advance the iterator to exactly target and return whether target has a value. target must be greater than or equal to the current doc ID and must be a valid doc ID, ie. ≥ 0 and < maxDoc.

Specified by:

advanceExact in class SortedNumericDoubleDocValues

Parameters:

doc - the target

Returns:

the next value

Throws:

IOException

docID

public int docID()

Specified by:

docID in class org.apache.lucene.search.DocIdSetIterator

nextDoc

public int nextDoc()
            throws IOException

Specified by:

nextDoc in class org.apache.lucene.search.DocIdSetIterator

Throws:

IOException

advance

public int advance(int target)
            throws IOException

Specified by:

advance in class org.apache.lucene.search.DocIdSetIterator

Throws:

IOException

cost

public long cost()

Specified by:
