Detailed Description

Asynchronous I/O Completion Callback.

The two socket classes (UDPSocket and TCPSocket) require that the I/O completion callback function have an operator() method with the appropriate signature. The classes are templates, any class with that method and signature can be passed as the callback object - there is no need for a base class defining the interface. However, some users of the socket classes do not use the asynchronous I/O operations, yet have to supply a template parameter. This is the reason for this class - it is the dummy template parameter.

◆ operator()() [1/2]

void isc::asiolink::DummyIOCallback::operator() ( boost::system::error_code )

inline

Asynchronous I/O callback method.

Should never be called, as this class is a convenience class provided for instances where a socket is required but it is known that no asynchronous operations will be carried out.
