DESCRIPTION
       The QNetworkOperation class provides common operations for network protocols.

       An object is created to describe the operation and the current state for each operation
       that a network protocol should process.

       For a detailed description of the Qt Network Architecture and how to implement and use
       network protocols in Qt, see the Qt Network Documentation.

       See also QNetworkProtocol and Input/Output and Networking.

MEMBER FUNCTION DOCUMENTATION
QNetworkOperation::QNetworkOperation ( QNetworkProtocol::Operation operation, const QString &
       arg0, const QString & arg1, const QString & arg2 )
       Constructs a network operation object. operation is the type of the operation, and arg0,
       arg1 and arg2 are the first three arguments of the operation. The state is initialized to
       QNetworkProtocol::StWaiting.

       See also QNetworkProtocol::Operation and QNetworkProtocol::State.

QNetworkOperation::QNetworkOperation ( QNetworkProtocol::Operation operation, const QByteArray &
       arg0, const QByteArray & arg1, const QByteArray & arg2 )
       Constructs a network operation object. operation is the type of the operation, and arg0,
       arg1 and arg2 are the first three raw data arguments of the operation. The state is
       initialized to QNetworkProtocol::StWaiting.

       See also QNetworkProtocol::Operation and QNetworkProtocol::State.

QNetworkOperation::~QNetworkOperation ()
       Destructor.

QString QNetworkOperation::arg ( int num ) const
       Returns the operation's num-th argument. If this argument was not already set, an empty
       string is returned.

       Example: network/networkprotocol/nntp.cpp.

int QNetworkOperation::errorCode () const
       Returns the error code for the last error that occurred.

void QNetworkOperation::free ()
       Sets this object to delete itself when it hasn't been used for one second.

       Because QNetworkOperation pointers are passed around a lot the QNetworkProtocol generally
       does not have enough knowledge to delete these at the correct time. If a QNetworkProtocol
       doesn't need an operation any more it will call this function instead.

       Note: you should never need to call the method yourself.

QNetworkProtocol::Operation QNetworkOperation::operation () const
       Returns the type of the operation.

QString QNetworkOperation::protocolDetail () const
       Returns a detailed error message for the last error. This must have been set using
       setProtocolDetail().

QByteArray QNetworkOperation::rawArg ( int num ) const
       Returns the operation's num-th raw data argument. If this argument was not already set, an
       empty bytearray is returned.

void QNetworkOperation::setArg ( int num, const QString & arg )
       Sets the network operation's num-th argument to arg.

void QNetworkOperation::setErrorCode ( int ec )
       Sets the error code to ec.

       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 QNetworkProtocol should be
       used.

       See also setProtocolDetail() and QNetworkProtocol::Error.

void QNetworkOperation::setProtocolDetail ( const QString & detail )
       If the operation failed, the error message can be specified as detail.

void QNetworkOperation::setRawArg ( int num, const QByteArray & arg )
       Sets the network operation's num-th raw data argument to arg.

void QNetworkOperation::setState ( QNetworkProtocol::State state )
       Sets the state of the operation object. This should be done by the network protocol during
       processing; at the end it should be set to QNetworkProtocol::StDone or
       QNetworkProtocol::StFailed, depending on success or failure.

       See also QNetworkProtocol::State.

QNetworkProtocol::State QNetworkOperation::state () const
       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.
