.SH DESCRIPTION
|
|
The QConstString class provides string objects using constant Unicode data.
|
|
.PP
|
|
In order to minimize copying, highly optimized applications can use QConstString to provide a TQString-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.
|
|
.PP
|
|
A QConstString is created with the QConstString constructor. The string held by the object can be obtained by calling string().
|

|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QConstString::QConstString ( const TQChar * unicode, uint length )"
|
|
Constructs a QConstString that uses the first \fIlength\fR Unicode characters in the array \fIunicode\fR. Any attempt to modify copies of the string will cause it to create a copy of the data, thus it remains forever unmodified.
|
|
.PP
|
|
The data in \fIunicode\fR is not copied. The caller must be able to guarantee that \fIunicode\fR will not be deleted or modified.
|
|
.SH "QConstString::~QConstString ()"
|
|
Destroys the QConstString, creating a copy of the data if other strings are still using it.
|
|
.SH "const TQString & QConstString::string () const"
|
|
Returns a constant string referencing the data passed during
|
|
construction.
