<hr><a name="details"></a><h2>Detailed Description</h2>
The QConstString class provides string objects using constant Unicode data.
<p> In order to minimize copying, highly optimized applications can
use QConstString to provide a <a href="qstring.html">QString</a>-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.
<p> A QConstString is created with the QConstString constructor. The
string held by the object can be obtained by calling <a href="#string">string</a>().
<p>See also <a href="text.html">Text Related Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QConstString"></a>QConstString::QConstString ( const <a href="qchar.html">QChar</a> * unicode, uint length )
</h3>
Constructs a QConstString that uses the first <em>length</em> Unicode
characters in the array <em>unicode</em>. Any attempt to modify copies
of the string will cause it to create a copy of the data, thus it
remains forever unmodified.
<p> The data in <em>unicode</em> is not copied. The caller must be able to
guarantee that <em>unicode</em> will not be deleted or modified.
<h3 class=fn><a name="~QConstString"></a>QConstString::~QConstString ()
</h3>
Destroys the QConstString, creating a copy of the data if other
strings are still using it.
<h3 class=fn>const <a href="qstring.html">QString</a> & <a name="string"></a>QConstString::string () const
</h3>
<p> Returns a constant string referencing the data passed during
construction.
