advanceExact
Description copied from class:DocValuesIterator
Advance the iterator to exactlytarget
and return whethertarget
has a value.target
must be greater than or equal to the currentdoc ID
and must be a valid doc ID, ie. ≥ 0 and <maxDoc
. After this method returns,DocIdSetIterator.docID()
returnstarget

advance
Description copied from class:DocIdSetIterator
Advances to the first beyond the current whose document number is greater than or equal to target, and returns the document number itself. Exhausts the iterator and returnsDocIdSetIterator.NO_MORE_DOCS
if target is greater than the highest document number in the set.The behavior of this method is undefined when called with
target ≤ current
, or after the iterator has exhausted. Both cases may result in unpredicted behavior.When
target > current
it behaves as if written:int advance(int target) { int doc; while ((doc = nextDoc()) < target) { } return doc; }
Some implementations are considerably more efficient than that.NOTE: this method may be called with
DocIdSetIterator.NO_MORE_DOCS
for efficiency by some Scorers. If your implementation cannot efficiently determine that it should exhaust, it is recommended that you check for that value in each call to this method.- Overrides:
