Detailed Description
This class can be used to efficiently search for occurrences of strings in a given string.
Theoretically speaking, a finite deterministic automaton is constructed which exactly accepts the strings that are to be recognized. In order to check whether a given string contains one of the strings that are being searched for the constructed automaton has to applied on each position in the given string.
