\inmodule QtCore
The QStringMatcher class holds a sequence of characters that can be quickly matched in a Unicode string.
This class is useful when you have a sequence of \l{QChar}s that you want to repeatedly match against some strings (perhaps in a loop), or when you want to search for the same sequence of characters multiple times in the same string. Using a matcher object and indexIn() is faster than matching a plain QString with QString::indexOf() if repeated matching takes place. This class offers no benefit if you are doing one-off string matches.
Create the QStringMatcher with the QString you want to search for. Then call indexIn() on the QString that you want to search.

Searches the string starting at str (of length length) from character position from (default 0, i.e. from the first character), for the string pattern() that was set in the constructor or in the most recent call to setPattern(). Returns the position where the pattern() matched in str, or -1 if no match was found.
