| [heading Description] |
| |
| The versions of `find_end` that return an iterator, return an iterator to the beginning of the last sub-sequence equal to `rng2` within `rng1`. |
| Equality is determined by `operator==` for non-predicate versions of `find_end`, and by satisfying `pred` in the predicate versions. The versions of `find_end` that return a `range_return`, defines `found` in the same manner as the returned iterator described above. |
| |
| [heading Definition] |
| |
| Defined in the header file `boost/range/algorithm/find_end.hpp` |
| |
| [heading Requirements] |
| |
| [*For the non-predicate versions:] |
| |
| * `ForwardRange1` is a model of the __forward_range__ Concept. |
| * `ForwardRange2` is a model of the __forward_range__ Concept. |
| * `ForwardRange1`'s value type is a model of the `EqualityComparableConcept`. |
| * `ForwardRange2`'s value type is a model of the `EqualityComparableConcept`. |
| * Objects of `ForwardRange1`'s value type can be compared for equality with objects of `ForwardRange2`'s value type. |
| |
| [*For the predicate versions:] |
| |
| * `ForwardRange1` is a model of the __forward_range__ Concept. |
| * `ForwardRange2` is a model of the __forward_range__ Concept. |
| * `BinaryPredicate` is a model of the `BinaryPredicateConcept`. |
| * `ForwardRange1`'s value type is convertible to `BinaryPredicate`'s first argument type. |
| * `ForwardRange2`'s value type is convertible to `BinaryPredicate`'s second argument type. |
| |
| [heading Complexity] |
| |
| The number of comparisons is proportional to `distance(rng1) * distance(rng2)`. If both `ForwardRange1` and `ForwardRange2` are models of `BidirectionalRangeConcept` then the average complexity is linear and the worst case is `distance(rng1) * distance(rng2)`. |
