Tyepof regex

[Tiberiu Gal]

what is the type returned by regex function?
I want to store a regex member because I need to reuse it 
multiple times.
Can this be done?

class A {

  protected SomeTypeName regexPattern;


 void load() {
      string str;
      // obtain a regex pattern and store it as str.
      regexPattern = regex( str );
  }

  bool matches() {
    // use regexPattern
 }

}
