<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> Note that <em>unicode</em> is <em>not</em> <em>copied</em>. The caller <em>must</em> be
able to guarantee that <em>unicode</em> will not be deleted or
modified. Since that is generally not the case with <tt>const</tt> strings
(they are references), this constructor demands a non-const pointer
even though it never modifies <em>unicode</em>.
<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.
