QConstString - A
#include <qstring.h>
Public Members
QConstString ( QChar * unicode, uint length )
~QConstString ()
const QString& string () const
DESCRIPTION
A QString which uses constant Unicode data.
In order to minimize copying, highly optimized
applications can use QConstString to provide a QString-
compatible object from existing Unicode data. It is then
the user's responsibility to make sure that the Unicode
data must exist for the entire lifetime of the
QConstString object.
MEMBER FUNCTION DOCUMENTATION
QConstString::QConstString ( QChar * unicode, uint length )
Constructs a QConstString that uses the first length
Unicode characters in the array unicode. Any attempt to
modify copies of the string will cause it to create a copy
of the data, thus it remains forever unmodified.
Note that unicode is not copied. The caller must be able
to guarantee that unicode will not be deleted or modified.
Since that is generally not the case with const strings
(they are references), this constructor demands a non-
const pointer even though it never modifies unicode.
QConstString::~QConstString ()
Destroys the QConstString, creating a copy of the data if
other strings are still using it.
const QString& QConstString::string () const
Returns a constant string referencing the data passed
during construction.
