|---|---|
int |
advance(int targetParentDocID)
Advances to the first beyond the current whose document number is greater
than or equal to target, and returns the document number itself.
|
boolean |
advanceExact(int targetParentDocID)
Advance the iterator to exactly
target and return whether
target has a value. |
long |
cost()
Returns the estimated cost of this
DocIdSetIterator. |
int |
docID()
Returns the following:
-1 if DocIdSetIterator.nextDoc() or
DocIdSetIterator.advance(int) were not called yet. |
void |
increment() |
long |
longValue()
Returns the numeric value for the current document ID.
|
int |
nextDoc()
Advances to the next document in the set and returns the doc it is
currently on, or
DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the
set.NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior. |

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.

target must be greater than or equal to the current
doc ID and must be a valid doc ID, ie. ≥ 0 and
< maxDoc.

This is generally an upper bound of the number of documents this iterator might match, but may be a rough heuristic, hardcoded value, or otherwise completely inaccurate.
