| 71 | [heading Description] | |
| 72 | ||
| 73 | The versions of `search` that return an iterator, return an iterator to the start of the first subsequence in `rng1` that is equal to the subsequence `rng2`. The `end(rng1)` is returned if no such subsequence exists in `rng1`. | |
| 74 | Equality is determined by `operator==` for non-predicate versions of `search`, and by satisfying `pred` in the predicate versions. | |
| 75 | ||
| 76 | The versions of `search` that return a `range_return`, defines `found` in the same manner as the returned iterator described above. | |
| 77 | ||
| 78 | [heading Definition] | |
| 79 | ||
| 80 | Defined in the header file `boost/range/algorithm/search.hpp` | |
| 81 | ||
| 82 | [heading Requirements] | |
| 83 | ||
| 84 | [*For the non-predicate versions:] | |
| 85 | ||
| 86 | * `ForwardRange1` is a model of the __forward_range__ Concept. | |
| 87 | * `ForwardRange2` is a model of the __forward_range__ Concept. | |
| 88 | * `ForwardRange1`'s value type is a model of the `EqualityComparableConcept`. | |
| 89 | * `ForwardRange2`'s value type is a model of the `EqualityComparableConcept`. | |
| 90 | * `ForwardRange1`s value type can be compared for equality with `ForwardRange2`'s value type. | |
| 91 | ||
| 92 | [*For the predicate versions:] | |
| 93 | ||
| 94 | * `ForwardRange1` is a model of the __forward_range__ Concept. | |
| 95 | * `ForwardRange2` is a model of the __forward_range__ Concept. | |
| 96 | * `BinaryPredicate` is a model of the `BinaryPredicateConcept`. | |
| 97 | * `ForwardRange1`'s value type is convertible to `BinaryPredicate`'s first argument type. | |
| 98 | * `ForwardRange2`'s value type is convertible to `BinaryPredicate`'s second argument type. | |
