Declared in `<bslstl_boyermoorehorspoolsearcher.h>`

Create a `BoyerMooreHorspoolSearcher` object having same state ‐‐ `needleFirst()`, `needleLast()`, `hash()`, and `equal()` ‐‐ as the specified `original` object, and that uses the currently installed default allocator to supply memory.

Create a `BoyerMooreHorspoolSearcher` object having same state ‐‐ `needleFirst()`, `needleLast()`, `hash()`, and `equal()` ‐‐ as the specified `original` object by moving (in constant time) the state of `original` to the new searcher. The allocator of `original` is propagated for use in the newly created searcher. The `original` object is left in an unspecified (valid) state.

Create a `BoyerMooreHorspoolSearcher` object having same state ‐‐ `needleFirst()`, `needleLast()`, `hash()`, and `equal()` ‐‐ as the specified `original` object. The specified `basicAllocator` is used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The state of `original` is moved (in constant time) to the new searcher if `basicAllocator == original.allocator()`, and is move‐inserted (in linear time) using `basicAllocator` otherwise. The `original` object is left in an unspecified (valid) state.

Create a `BoyerMooreHorspoolSearcher` object having same state ‐‐ `needleFirst()`, `needleLast()`, `hash()`, and `equal()` ‐‐ as the specified `original` object. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used.

Create a `BoyerMooreHorspoolSearcher` object that can search for the sequence of `value_type` values found in the specified range `[needleFirst, needleLast)]`. Generate meta‐data and save for use by `operator()`. The complexity of this process is O(M) where M is the length of the "needle". Optionally specify a `hash` functor mapping mis‐matched values to the size of the next step in the search ‐‐ as large as, `needleLast ‐ needleFirst`. Optionally specify an `equal` functor for use with `hash` and for use by `operator()`. See {Requirements for `HASH` and `EQUAL`}. Optionally specify `basicAllocator` to supply memory. If `basicAllocator` is 0 or not supplied, the currently installed default allocator is used. The behavior is undefined unless `needleFirst` can be advanced to `needleLast`.
