Detailed Description

The DummySocket class is a concrete derived class of IOSocket that is not associated with any real socket.

This main purpose of this class is tests, where it may be desirable to instantiate an IOSocket object without involving system resource allocation such as real network sockets.

Constructor & Destructor Documentation

isc::asiolink::DummySocket::DummySocket ( const int  protocol )

inline

Constructor from the protocol number.

The protocol must validly identify a standard network protocol. For example, to specify TCP protocol must be IPPROTO_TCP.

Parameters

protocol

The network protocol number for the socket.

Definition at line 31 of file io_socket.cc.

Member Function Documentation

virtual int isc::asiolink::DummySocket::getNative ( ) const

inlinevirtual

A dummy derived method of IOSocket::getNative().

This version of method always returns -1 as the object is not associated with a real (native) socket.

Implements isc::asiolink::IOSocket.

Definition at line 37 of file io_socket.cc.

virtual int isc::asiolink::DummySocket::getProtocol ( ) const

inlinevirtual

Return the transport protocol of the socket.

Currently, it returns IPPROTO_UDP for UDP sockets, and IPPROTO_TCP for TCP sockets.

This method never throws an exception.

Returns

IPPROTO_UDP for UDP sockets

IPPROTO_TCP for TCP sockets

Implements isc::asiolink::IOSocket.
