It is -normally used with a <a href="qtextstream.html">TQTextStream</a> or a <a href="qdatastream.html">TQDataStream</a>. TQBuffer has an -associated TQByteArray which holds the buffer data. The <a href="qiodevice.html#size">size</a>() of -the buffer is automatically adjusted as data is written. -<p> The constructor <tt>TQBuffer(TQByteArray)</tt> creates a TQBuffer using an -existing byte array. The byte array can also be set with -<a href="#setBuffer">setBuffer</a>(). Writing to the TQBuffer will modify the original byte -array because TQByteArray is <a href="shclass.html">explicitly - shared.</a> -<p> Use <a href="qiodevice.html#open">open</a>() to open the buffer before use and to set the mode -(read-only, write-only, etc.). <a href="qiodevice.html#close">close</a>() closes the buffer. The -buffer must be closed before reopening or calling setBuffer(). -<p> A common way to use TQBuffer is through <a href="qdatastream.html">TQDataStream</a> or <a href="qtextstream.html">TQTextStream</a>, which have constructors that take a TQBuffer -parameter. For convenience, there are also TQDataStream and -<a href="qtextstream.html">TQTextStream</a> constructors that take a <a href="qbytearray.html">TQByteArray</a> parameter. These -constructors create and open an internal TQBuffer. -<p> Note that TQTextStream can also operate on a <a href="qstring.html">TQString</a> (a Unicode -string); a TQBuffer cannot. -<p> You can also use TQBuffer directly through the standard <a href="qiodevice.html">TQIODevice</a> -functions <a href="qiodevice.html#readBlock">readBlock</a>(), <a href="#writeBlock">writeBlock</a>() <a href="qiodevice.html#readLine">readLine</a>(), <a href="qiodevice.html#at">at</a>(), <a href="qiodevice.html#getch">getch</a>(), -<a href="qiodevice.html#putch">putch</a>() and <a href="qiodevice.html#ungetch">ungetch</a>(). -<p> <p>See also <a href="qfile.html">TQFile</a>, <a href="qdatastream.html">TQDataStream</a>, <a href="qtextstream.html">TQTextStream</a>, <a href="qbytearray.html">TQByteArray</a>, <a href="shclass.html">Shared Classes</a>, <a href="collection.html">Collection Classes</a>, and <a href="io.html">Input/Output and Networking</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQBuffer"></a>TQBuffer::TQBuffer () -</h3> -Constructs an empty buffer. - -<h3 class=fn><a name="TQBuffer-2"></a>TQBuffer::TQBuffer ( <a href="qbytearray.html">TQByteArray</a> buf ) -</h3> -Constructs a buffer that operates on <em>buf</em>. -<p> If you open the buffer in write mode (<a href="qfile.html#open"><a href="qfile.html#open">IO_WriteOnly</a></a> or -<a href="qfile.html#open">IO_ReadWrite</a>) and write something into the buffer, <em>buf</em> -will be modified. -<p> Example: -<pre> - <a href="qcstring.html">TQCString</a> str = "abc"; - TQBuffer b( str ); - b.<a href="qiodevice.html#open">open</a>( IO_WriteOnly ); - b.<a href="qiodevice.html#at">at</a>( 3 ); // position at the 4th character (the terminating \0) - b.<a href="#writeBlock">writeBlock</a>( "def", 4 ); // write "def" including the terminating \0 - b.<a href="qiodevice.html#close">close</a>(); - // Now, str == "abcdef" with a terminating \0 - </pre> - -<p> <p>See also <a href="#setBuffer">setBuffer</a>(). - -<h3 class=fn><a name="~TQBuffer"></a>TQBuffer::~TQBuffer () -</h3> -Destroys the buffer. - -<h3 class=fn><a href="qbytearray.html">TQByteArray</a> <a name="buffer"></a>TQBuffer::buffer () const -</h3> - -<p> Returns this buffer's byte array. -<p> <p>See also <a href="#setBuffer">setBuffer</a>(). - -<h3 class=fn>bool <a name="setBuffer"></a>TQBuffer::setBuffer ( <a href="qbytearray.html">TQByteArray</a> buf ) -</h3> -Replaces the buffer's contents with <em>buf</em> and returns TRUE. -<p> Does nothing (and returns FALSE) if <a href="qiodevice.html#isOpen">isOpen</a>() is TRUE. -<p> Note that if you open the buffer in write mode (<a href="qfile.html#open"><a href="qfile.html#open">IO_WriteOnly</a></a> or -<a href="qfile.html#open">IO_ReadWrite</a>) and write something into the buffer, <em>buf</em> is also -modified because <a href="qbytearray.html">TQByteArray</a> is an <a href="shclass.html#explicitly-shared">explicitly shared</a> class. -<p> <p>See also <a href="#buffer">buffer</a>(), <a href="qiodevice.html#open">open</a>(), and <a href="qiodevice.html#close">close</a>(). - -<h3 class=fn>Q_LONG <a name="writeBlock"></a>TQBuffer::writeBlock ( const char * p, Q_ULONG len )<tt> [virtual]</tt> -</h3> -Writes <em>len</em> bytes from <em>p</em> into the buffer at the current -index position, overwriting any characters there and extending the -buffer if necessary.
