MODULE NOTES:
|
|
|
|
See nsStr.h for a more general description of string classes.
|
|
|
|
This version of the nsString class offers many improvements over the
|
|
original version:
|
|
1. Wide and narrow chars
|
|
2. Allocators
|
|
3. Much smarter autostrings
|
|
4. Subsumable strings
|

It differs from a normal string in that it doesn't use normal

Instead, it "steals" the contents of the source string.
