Common::String Class Reference

#include <str.h>

List of all members.


Detailed Description

Simple string class for ScummVM. Provides automatic storage managment, and overloads several operators in a 'natural' fashion, mimicking the std::string class. Even provides simple iterators.

This class tries to avoid allocating lots of small blocks on the heap, since that is inefficient on several platforms supported by ScummVM. Instead, small strings are stored 'inside' the string object (i.e. on the stack, for stack allocated objects), and only for strings exceeding a certain length do we allocate a buffer on the heap.
