Method Detail

resize

protected final void resize(int newSize)

Set the docValueCount() and ensure that the values array can store at least that many entries.

sort

protected final void sort()

Sort values that are stored between offsets 0 and count of values.

docValueCount

public final int docValueCount()

Description copied from class: SortedNumericDocValues

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

Specified by:

docValueCount in class SortedNumericDocValues

nextValue

public final long nextValue()

Description copied from class: SortedNumericDocValues

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

Specified by:

nextValue in class SortedNumericDocValues

advanceExact

public abstract boolean advanceExact(int target)
                              throws IOException

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. After this method returns, DocIdSetIterator.docID() returns target.

Throws:

IOException
