Module Name:
|
|
|
|
GENERIC_STRING
|
|
|
|
Abstract:
|
|
|
|
This module contains the definition for the GENERIC_STRING class.
|
|
|
|
Environment:
|
|
|
|
ULIB, User Mode
|
|
|
|
Notes:
|
|
|
|
A GENERIC_STRING is the base class for all string classes. This
|
|
base class provides a basic wide-character interface.
|
|
|
|
A string is a finite, ordered sequence of wide characters. Note
|
|
that a GENERIC_STRING is NOT necessarily null-terminated.
|
|
|
|
Individual characters within a string are indexed by a number of
|
|
type CHNUM (CHaracter NUMber). This index is zero-based.
|
|
|
|
There are three special symbols that are widely used in the ULIB
|
|
strings world:
|
|
|
|
INVALID_CHAR This symbol represents an invalid wide character.
|
|
|
|
INVALID_CHNUM This symbol represents an invalid CHNUM index within
|
|
a GENERIC_STRING.
|
|
|
|
TO_END This symbol means "up to the end of the string", and
|
|
is used a lot as a default value in those methods
|
|
that accept a length argument.
