FuncIterRangesOp CompareStatus CS_SUBSET First is subset of second iterator. CS_DISJOINT Intersection is empty. CS_NONE Neither of the above. Comapre two iterators with each other. class I unsigned int unsigned int Gecode::Iter::Ranges::size (I &i) size I & i Size of all ranges of range iterator i. class I class J bool bool Gecode::Iter::Ranges::equal (I &i, J &j) equal I & i J & j Check whether range iterators i and j are equal. class I class J bool bool Gecode::Iter::Ranges::subset (I &i, J &j) subset I & i J & j Check whether range iterator i is subset of range iterator j. class I class J bool bool Gecode::Iter::Ranges::disjoint (I &i, J &j) disjoint I & i J & j Check whether range iterators i and j are disjoint. class I class J CompareStatus CompareStatus Gecode::Iter::Ranges::compare (I &i, J &j) compare I & i J & j Check whether range iterator i is a subset of j, or whether they are disjoint.
