<h2>Detailed Description</h2>
<p>The Q3NetworkOperation class provides common operations for network protocols.</p>
<p>An object is created to describe the operation and the current state for each operation that a network protocol should process.</p>
<p>See also <a href="q3networkprotocol.html">Q3NetworkProtocol</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="Q3NetworkOperation"></a>Q3NetworkOperation::Q3NetworkOperation ( <a href="q3networkprotocol.html#Operation-enum">Q3NetworkProtocol::Operation</a> <i>operation</i>, const <a href="qstring.html">QString</a> & <i>arg0</i>, const <a href="qstring.html">QString</a> & <i>arg1</i>, const <a href="qstring.html">QString</a> & <i>arg2</i> )</h3>
<p>Constructs a network operation object. <i>operation</i> is the type of the operation, and <i>arg0</i>, <i>arg1</i> and <i>arg2</i> are the first three arguments of the operation. The state is initialized to <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::StWaiting</a>.</p>
<p>See also <a href="q3networkprotocol.html#Operation-enum">Q3NetworkProtocol::Operation</a> and <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::State</a>.</p>
<h3 class="fn"><a name="Q3NetworkOperation-2"></a>Q3NetworkOperation::Q3NetworkOperation ( <a href="q3networkprotocol.html#Operation-enum">Q3NetworkProtocol::Operation</a> <i>operation</i>, const <a href="qbytearray.html">QByteArray</a> & <i>arg0</i>, const <a href="qbytearray.html">QByteArray</a> & <i>arg1</i>, const <a href="qbytearray.html">QByteArray</a> & <i>arg2</i> )</h3>
<p>Constructs a network operation object. <i>operation</i> is the type of the operation, and <i>arg0</i>, <i>arg1</i> and <i>arg2</i> are the first three raw data arguments of the operation. The state is initialized to <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::StWaiting</a>.</p>
<p>See also <a href="q3networkprotocol.html#Operation-enum">Q3NetworkProtocol::Operation</a> and <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::State</a>.</p>
<h3 class="fn"><a name="dtor.Q3NetworkOperation"></a>Q3NetworkOperation::~Q3NetworkOperation ()</h3>
<p>Destructor.</p>
<h3 class="fn"><a name="arg"></a><a href="qstring.html">QString</a> Q3NetworkOperation::arg ( int <i>num</i> ) const</h3>
<p>Returns the operation's <i>num</i>-th argument. If this argument was not already set, an empty string is returned.</p>
<p>See also <a href="q3networkoperation.html#setArg">setArg</a>().</p>
<h3 class="fn"><a name="errorCode"></a>int Q3NetworkOperation::errorCode () const</h3>
<p>Returns the error code for the last error that occurred.</p>
<p>See also <a href="q3networkoperation.html#setErrorCode">setErrorCode</a>().</p>
<h3 class="fn"><a name="free"></a>void Q3NetworkOperation::free ()</h3>
<p>Sets this object to delete itself when it hasn't been used for one second.</p>
<p>Because <a href="q3networkoperation.html">Q3NetworkOperation</a> pointers are passed around a lot the <a href="q3networkprotocol.html">Q3NetworkProtocol</a> generally does not have enough knowledge to delete these at the correct time. If a <a href="q3networkprotocol.html">Q3NetworkProtocol</a> doesn't need an operation any more it will call this function instead.</p>
<p>Note: you should never need to call the method yourself.</p>
<h3 class="fn"><a name="operation"></a><a href="q3networkprotocol.html#Operation-enum">Q3NetworkProtocol::Operation</a> Q3NetworkOperation::operation () const</h3>
<p>Returns the type of the operation.</p>
<h3 class="fn"><a name="protocolDetail"></a><a href="qstring.html">QString</a> Q3NetworkOperation::protocolDetail () const</h3>
<p>Returns a detailed error message for the last error. This must have been set using <a href="q3networkoperation.html#setProtocolDetail">setProtocolDetail</a>().</p>
<p>See also <a href="q3networkoperation.html#setProtocolDetail">setProtocolDetail</a>().</p>
<h3 class="fn"><a name="rawArg"></a><a href="qbytearray.html">QByteArray</a> Q3NetworkOperation::rawArg ( int <i>num</i> ) const</h3>
<p>Returns the operation's <i>num</i>-th raw data argument. If this argument was not already set, an empty bytearray is returned.</p>
<p>See also <a href="q3networkoperation.html#setRawArg">setRawArg</a>().</p>
<h3 class="fn"><a name="setArg"></a>void Q3NetworkOperation::setArg ( int <i>num</i>, const <a href="qstring.html">QString</a> & <i>arg</i> )</h3>
<p>Sets the network operation's <i>num</i>-th argument to <i>arg</i>.</p>
<p>See also <a href="q3networkoperation.html#arg">arg</a>().</p>
<h3 class="fn"><a name="setErrorCode"></a>void Q3NetworkOperation::setErrorCode ( int <i>ec</i> )</h3>
<p>Sets the error code to <i>ec</i>.</p>
<p>If the operation failed, the protocol should set an error code to describe the error in more detail. If possible, one of the error codes defined in <a href="q3networkprotocol.html">Q3NetworkProtocol</a> should be used.</p>
<p>See also <a href="q3networkoperation.html#errorCode">errorCode</a>(), <a href="q3networkoperation.html#setProtocolDetail">setProtocolDetail</a>(), and <a href="q3networkprotocol.html#Error-enum">Q3NetworkProtocol::Error</a>.</p>
<h3 class="fn"><a name="setProtocolDetail"></a>void Q3NetworkOperation::setProtocolDetail ( const <a href="qstring.html">QString</a> & <i>detail</i> )</h3>
<p>If the operation failed, the error message can be specified as <i>detail</i>.</p>
<p>See also <a href="q3networkoperation.html#protocolDetail">protocolDetail</a>().</p>
<h3 class="fn"><a name="setRawArg"></a>void Q3NetworkOperation::setRawArg ( int <i>num</i>, const <a href="qbytearray.html">QByteArray</a> & <i>arg</i> )</h3>
<p>Sets the network operation's <i>num</i>-th raw data argument to <i>arg</i>.</p>
<p>See also <a href="q3networkoperation.html#rawArg">rawArg</a>().</p>
<h3 class="fn"><a name="setState"></a>void Q3NetworkOperation::setState ( <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::State</a> <i>state</i> )</h3>
<p>Sets the <i>state</i> of the operation object. This should be done by the network protocol during processing; at the end it should be set to <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::StDone</a> or <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::StFailed</a>, depending on success or failure.</p>
<p>See also <a href="q3networkoperation.html#state">state</a>() and <a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::State</a>.</p>
<h3 class="fn"><a name="state"></a><a href="q3networkprotocol.html#State-enum">Q3NetworkProtocol::State</a> Q3NetworkOperation::state () const</h3>
<p>Returns the state of the operation. You can determine whether an operation is still waiting to be processed, is being processed, has been processed successfully, or failed.</p>
<p>See also <a href="q3networkoperation.html#setState">setState</a>().</p>
