<hr><a name="details"></a><h2>Detailed Description</h2>
The QByteArray class provides an array of bytes.
<p>
<p> The QByteArray class provides an <a href="shclass.html#explicitly-shared">explicitly shared</a> array of bytes.
It is useful for manipulating memory areas with custom data.
QByteArray is implemented as a <a href="qmemarray.html">QMemArray</a><char>. See the <a href="qmemarray.html">QMemArray</a> documentation for further information.
<p>See also <a href="collection.html">Collection Classes</a> and <a href="tools.html">Non-GUI Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QByteArray"></a>QByteArray::QByteArray ()
</h3>
<p> Constructs an empty QByteArray.
<h3 class=fn><a name="QByteArray-2"></a>QByteArray::QByteArray ( int size )
</h3>
<p> Constructs a QByteArray of size <em>size</em>.
<hr><h2>Related Functions</h2>
<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="qCompress"></a>qCompress ( const <a href="qbytearray.html">QByteArray</a> & data )
</h3>
<p>
<p> Compresses the array <em>data</em> and returns the compressed byte
array using zlib.
<p> <p>See also <a href="#qUncompress">qUncompress</a>().
<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="qCompress-2"></a>qCompress ( const uchar * data, int nbytes )
</h3>
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Compresses the array <em>data</em> which is <em>nbytes</em> long and returns the
compressed byte array.
<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="qUncompress"></a>qUncompress ( const <a href="qbytearray.html">QByteArray</a> & data )
</h3>
<p>
<p> Uncompresses the array <em>data</em> and returns the uncompressed byte
array.
<p> Returns an empty QByteArray if the input data was corrupt.
<p> <p>See also <a href="#qCompress">qCompress</a>().
<h3 class=fn><a href="qbytearray.html">QByteArray</a> <a name="qUncompress-2"></a>qUncompress ( const uchar * data, int nbytes )
</h3>
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Uncompresses the array <em>data</em> which is <em>nbytes</em> long and returns
the uncompressed byte array.
