Detailed Description

An internal support class for ToString().

StrFormat manages the formatting of arbitrary length strings. The class starts with a default internal fixed size buffer and moves to dynamic allocation from the heap when that is exceeded. Constructing the class on the stack will result in its most efficient use. This class is meant to be used as a helper class, and not for the permanent storage of string data.

char* indexString(U32 index)
{
   StrFormat format("Index: %d",index);
   char* str = new char[format.size()];
   format.copy(str);
   return str;
}
