.SH DESCRIPTION
The TQNetworkOperation class provides common operations for network protocols.
.PP
An object is created to describe the operation and the current state for each operation that a network protocol should process.
.PP
For a detailed description of the TQt Network Architecture and how to implement and use network protocols in Qt, see the TQt Network Documentation.
.PP
See also TQNetworkProtocol and Input/Output and Networking.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQNetworkOperation::TQNetworkOperation ( TQNetworkProtocol::Operation operation, const TQString & arg0, const TQString & arg1, const TQString & arg2 )"
Constructs a network operation object. \fIoperation\fR is the type of the operation, and \fIarg0\fR, \fIarg1\fR and \fIarg2\fR are the first three arguments of the operation. The state is initialized to TQNetworkProtocol::StWaiting.
.PP
See also TQNetworkProtocol::Operation and TQNetworkProtocol::State.
.SH "TQNetworkOperation::TQNetworkOperation ( TQNetworkProtocol::Operation operation, const TQByteArray & arg0, const TQByteArray & arg1, const TQByteArray & arg2 )"
Constructs a network operation object. \fIoperation\fR is the type of the operation, and \fIarg0\fR, \fIarg1\fR and \fIarg2\fR are the first three raw data arguments of the operation. The state is initialized to TQNetworkProtocol::StWaiting.
.PP
See also TQNetworkProtocol::Operation and TQNetworkProtocol::State.
.SH "TQNetworkOperation::~TQNetworkOperation ()"
Destructor.
.SH "TQString TQNetworkOperation::arg ( int num ) const"
Returns the operation's \fInum\fR-th argument. If this argument was not already set, an empty string is returned.
.PP
Example: network/networkprotocol/nntp.cpp.
.SH "int TQNetworkOperation::errorCode () const"
Returns the error code for the last error that occurred.
.SH "void TQNetworkOperation::free ()"
Sets this object to delete itself when it hasn't been used for one second.
.PP
Because TQNetworkOperation pointers are passed around a lot the TQNetworkProtocol 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.
.PP
Note: you should never need to call the method yourself.
.SH "TQNetworkProtocol::Operation TQNetworkOperation::operation () const"
Returns the type of the operation.
.SH "TQString TQNetworkOperation::protocolDetail () const"
Returns a detailed error message for the last error. This must have been set using setProtocolDetail().
.SH "TQByteArray TQNetworkOperation::rawArg ( int num ) const"
Returns the operation's \fInum\fR-th raw data argument. If this argument was not already set, an empty bytearray is returned.
.SH "void TQNetworkOperation::setArg ( int num, const TQString & arg )"
Sets the network operation's \fInum\fR-th argument to \fIarg\fR.
.SH "void TQNetworkOperation::setErrorCode ( int ec )"
Sets the error code to \fIec\fR.
.PP
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 TQNetworkProtocol should be used.
.PP
See also setProtocolDetail() and TQNetworkProtocol::Error.
.SH "void TQNetworkOperation::setProtocolDetail ( const TQString & detail )"
If the operation failed, the error message can be specified as \fIdetail\fR.
.SH "void TQNetworkOperation::setRawArg ( int num, const TQByteArray & arg )"
Sets the network operation's \fInum\fR-th raw data argument to \fIarg\fR.
.SH "void TQNetworkOperation::setState ( TQNetworkProtocol::State state )"
Sets the \fIstate\fR 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.
.PP
See also TQNetworkProtocol::State.
.SH "TQNetworkProtocol::State TQNetworkOperation::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.
