BloombergLP::bslstl::BoyerMooreHorspoolSearcher::BoyerMooreHorspoolSearcher

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.
