## 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

## ◆ DummySocket()

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

## ◆ getNative()

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

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.

## ◆ getProtocol()

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

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.
