QConstString - String objects using constant Unicode data
All the functions in this class are reentrant when Qt is built with thread support.</p>
QConstString ( const QChar * unicode, uint length )
const QString & string () const
The QConstString class provides string objects using 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
programmer's responsibility to ensure that the Unicode data exists for the entire lifetime
of the QConstString object.
A QConstString is created with the QConstString constructor. The string held by the object
can be obtained by calling string().

MEMBER FUNCTION DOCUMENTATION
QConstString::QConstString ( const 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.
The data in unicode is not copied. The caller must be able to guarantee that unicode will
not be deleted or modified.
Destroys the QConstString, creating a copy of the data if other strings are still using
const QString & QConstString::string () const
Returns a constant string referencing the data passed during construction.
