The Q3NetworkOperation 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.
See also Q3NetworkProtocol.
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 Q3NetworkProtocol::StWaiting.
See also Q3NetworkProtocol::Operation and Q3NetworkProtocol::State.
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 Q3NetworkProtocol::StWaiting.
See also Q3NetworkProtocol::Operation and Q3NetworkProtocol::State.
Destructor.
Returns the operation's num-th argument. If this argument was not already set, an empty string is returned.
See also setArg().
Returns the error code for the last error that occurred.
See also setErrorCode().
Sets this object to delete itself when it hasn't been used for one second.
Because Q3NetworkOperation pointers are passed around a lot the Q3NetworkProtocol generally does not have enough knowledge to delete these at the correct time. If a Q3NetworkProtocol doesn't need an operation any more it will call this function instead.
Note: you should never need to call the method yourself.
Returns the type of the operation.
Returns a detailed error message for the last error. This must have been set using setProtocolDetail().
See also setProtocolDetail().
Returns the operation's num-th raw data argument. If this argument was not already set, an empty bytearray is returned.
See also setRawArg().
Sets the network operation's num-th argument to arg.
See also arg().
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 Q3NetworkProtocol should be used.
See also errorCode(), setProtocolDetail(), and Q3NetworkProtocol::Error.
If the operation failed, the error message can be specified as detail.
See also protocolDetail().
Sets the network operation's num-th raw data argument to arg.
See also rawArg().
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 Q3NetworkProtocol::StDone or Q3NetworkProtocol::StFailed, depending on success or failure.
See also state() and Q3NetworkProtocol::State.
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.
See also setState().
