NAME

6       QConstString - String objects using constant Unicode data

SYNOPSIS

9       All the functions in this class are reentrant when Qt is built with
10       thread support.</p>

DESCRIPTION

20       The QConstString class provides string objects using constant Unicode
21       data.
22
23       In order to minimize copying, highly optimized applications can use
24       QConstString to provide a QString-compatible object from existing
25       Unicode data. It is then the programmer's responsibility to ensure that
26       the Unicode data exists for the entire lifetime of the QConstString
27       object.
28
29       A QConstString is created with the QConstString constructor. The string
30       held by the object can be obtained by calling string().

MEMBER FUNCTION DOCUMENTATION

QConstString::QConstString ( const QChar * unicode, uint length )
36       Constructs a QConstString that uses the first length Unicode characters
37       in the array unicode. Any attempt to modify copies of the string will
38       cause it to create a copy of the data, thus it remains forever
39       unmodified.
40
41       The data in unicode is not copied. The caller must be able to guarantee
42       that unicode will not be deleted or modified.
43

QConstString::~QConstString ()
45       Destroys the QConstString, creating a copy of the data if other strings
46       are still using it.
47

const QString & QConstString::string () const
49       Returns a constant string referencing the data passed during
50       construction.
