Introduction

Exposes a TypeWrapper for the Python str type.

Classes

Class str

Exposes the string methods of Python's built-in str type. The semantics of the constructors and member functions defined below, except for the two-argument constructors which construct str objects from a range of characters, can be fully understood by reading the TypeWrapper concept definition. Since str is publicly derived from object, the public object interface applies to str instances as well.
