The TQConstString class provides string objects using constant Unicode data.
|
||
|
|
<p> In order to minimize copying, highly optimized applications can
|
||
|
6 months ago
|
use TQConstString to provide a <a href="tqstring.html">TQString</a>-compatible object from
|
||
|
13 years ago
|
existing Unicode data. It is then the programmer's responsibility
|
||
|
|
to ensure that the Unicode data exists for the entire lifetime of
|
||
|
|
the TQConstString object.
|
||
|
|
<p> A TQConstString is created with the TQConstString 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>.

<h3 class=fn><a name="TQConstString"></a>TQConstString::TQConstString ( const <a href="tqchar.html">TQChar</a> * unicode, uint length )
|

|
13 years ago
|
</h3>
|
||
|
|
Constructs a TQConstString 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="~TQConstString"></a>TQConstString::~TQConstString ()
|
||
|
|
</h3>
|
||
|
|
Destroys the TQConstString, creating a copy of the data if other
|
||
|
|
strings are still using it.

|

|
|
|

<p> Returns a constant string referencing the data passed during

construction.
