<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The TQNetworkOperation 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> For a detailed description of the TQt Network Architecture and how
to implement and use network protocols in TQt, see the <a href="network.html">TQt Network Documentation</a>.
<p> <p>See also <a href="qnetworkprotocol.html">TQNetworkProtocol</a> and <a href="io.html">Input/Output and Networking</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQNetworkOperation"></a>TQNetworkOperation::TQNetworkOperation ( <a href="qnetworkprotocol.html#Operation-enum">TQNetworkProtocol::Operation</a> operation, const <a href="qstring.html">TQString</a> & arg0, const <a href="qstring.html">TQString</a> & arg1, const <a href="qstring.html">TQString</a> & arg2 )
</h3>
Constructs a network operation object. <em>operation</em> is the type of
the operation, and <em>arg0</em>, <em>arg1</em> and <em>arg2</em> are the first
three arguments of the operation. The state is initialized to
TQNetworkProtocol::StWaiting.
<p> <p>See also <a href="qnetworkprotocol.html#Operation-enum">TQNetworkProtocol::Operation</a> and <a href="qnetworkprotocol.html#State-enum">TQNetworkProtocol::State</a>.
<h3 class=fn><a name="TQNetworkOperation-2"></a>TQNetworkOperation::TQNetworkOperation ( <a href="qnetworkprotocol.html#Operation-enum">TQNetworkProtocol::Operation</a> operation, const <a href="qbytearray.html">TQByteArray</a> & arg0, const <a href="qbytearray.html">TQByteArray</a> & arg1, const <a href="qbytearray.html">TQByteArray</a> & arg2 )
</h3>
Constructs a network operation object. <em>operation</em> is the type of
the operation, and <em>arg0</em>, <em>arg1</em> and <em>arg2</em> are the first
three raw data arguments of the operation. The state is
initialized to TQNetworkProtocol::StWaiting.
<p> <p>See also <a href="qnetworkprotocol.html#Operation-enum">TQNetworkProtocol::Operation</a> and <a href="qnetworkprotocol.html#State-enum">TQNetworkProtocol::State</a>.
<h3 class=fn><a name="~TQNetworkOperation"></a>TQNetworkOperation::~TQNetworkOperation ()
</h3>
Destructor.
<h3 class=fn><a href="qstring.html">TQString</a> <a name="arg"></a>TQNetworkOperation::arg ( int num ) const
</h3>
Returns the operation's <em>num</em>-th argument. If this argument was
not already set, an empty string is returned.
<p>Example: <a href="networkprotocol-example.html#x672">network/networkprotocol/nntp.cpp</a>.
<h3 class=fn>int <a name="errorCode"></a>TQNetworkOperation::errorCode () const
</h3>
Returns the error code for the last error that occurred.
<h3 class=fn>void <a name="free"></a>TQNetworkOperation::free ()
</h3>
Sets this object to delete itself when it hasn't been used for one
second.
<p> Because TQNetworkOperation pointers are passed around a lot the
<a href="qnetworkprotocol.html">TQNetworkProtocol</a> generally does not have enough knowledge to
delete these at the correct time. If a TQNetworkProtocol doesn't
need an operation any more it will call this function instead.
<p> Note: you should never need to call the method yourself.
<h3 class=fn><a href="qnetworkprotocol.html#Operation-enum">TQNetworkProtocol::Operation</a> <a name="operation"></a>TQNetworkOperation::operation () const
</h3>
Returns the type of the operation.
<h3 class=fn><a href="qstring.html">TQString</a> <a name="protocolDetail"></a>TQNetworkOperation::protocolDetail () const
</h3>
Returns a detailed error message for the last error. This must
have been set using <a href="#setProtocolDetail">setProtocolDetail</a>().
<h3 class=fn><a href="qbytearray.html">TQByteArray</a> <a name="rawArg"></a>TQNetworkOperation::rawArg ( int num ) const
</h3>
Returns the operation's <em>num</em>-th raw data argument. If this
argument was not already set, an empty bytearray is returned.
<h3 class=fn>void <a name="setArg"></a>TQNetworkOperation::setArg ( int num, const <a href="qstring.html">TQString</a> & arg )
</h3>
Sets the network operation's <em>num</em>-th argument to <em>arg</em>.
<h3 class=fn>void <a name="setErrorCode"></a>TQNetworkOperation::setErrorCode ( int ec )
</h3>
Sets the error code to <em>ec</em>.
<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="qnetworkprotocol.html">TQNetworkProtocol</a> should be used.
<p> <p>See also <a href="#setProtocolDetail">setProtocolDetail</a>() and <a href="qnetworkprotocol.html#Error-enum">TQNetworkProtocol::Error</a>.
<h3 class=fn>void <a name="setProtocolDetail"></a>TQNetworkOperation::setProtocolDetail ( const <a href="qstring.html">TQString</a> & detail )
</h3>
If the operation failed, the error message can be specified as <em>detail</em>.
<h3 class=fn>void <a name="setRawArg"></a>TQNetworkOperation::setRawArg ( int num, const <a href="qbytearray.html">TQByteArray</a> & arg )
</h3>
Sets the network operation's <em>num</em>-th raw data argument to <em>arg</em>.
<h3 class=fn>void <a name="setState"></a>TQNetworkOperation::setState ( <a href="qnetworkprotocol.html#State-enum">TQNetworkProtocol::State</a> state )
</h3>
Sets the <em>state</em> of the operation object. This should be done by
the network protocol during processing; at the end it should be
set to TQNetworkProtocol::StDone or TQNetworkProtocol::StFailed,
depending on success or failure.
<p> <p>See also <a href="qnetworkprotocol.html#State-enum">TQNetworkProtocol::State</a>.
<h3 class=fn><a href="qnetworkprotocol.html#State-enum">TQNetworkProtocol::State</a> <a name="state"></a>TQNetworkOperation::state () const
</h3>
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.
