Detailed Description

template<class T = char>
class utl::BoyerMooreSearch< T >

Boyer-Moore string search.

The Boyer-Moore string search algorithm is extremely fast, but requires some initial setup. Due to the cost associated with the initial setup, you should use BoyerMooreSearch in the following situations:

the string to be searched is long
many strings are to be searched for a single string
