nsStringHeader Class Reference

List of all members.


Detailed Description

This structure precedes the string buffers "we" allocate. It may be the case that nsTSubstring::mData does not point to one of these special buffers. The mFlags member variable distinguishes the buffer type.

When this header is in use, it enables reference counting, and capacity tracking. NOTE: A string buffer can be modified only if its reference count is 1.
