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
|

The subsumestr class is very unusual.

|
It differs from a normal string in that it doesn't use normal
|
|
copy semantics when another string is assign to this.
|
|
Instead, it "steals" the contents of the source string.
|
|
|
|
This is very handy for returning nsString classes as part of
|
|
an operator+(...) for example, in that it cuts down the number
|
|
of copy operations that must occur.
|

You should probably not use this class unless you really know

what you're doing.
