Detailed Description

Base class for sink applications.

This class can be used as a base class for sink applications. A sink application is an application that is primarily used to only receive or echo packets.

The main purpose of this base class application public API is to hold attributes for the local (IPv4 or IPv6) address and port to bind to.

There are three ways that the port value can be configured. First, and most typically, through the use of a socket address (InetSocketAddress or Inet6SocketAddress) that is configured as the Local address to bind to. Second, through direct configuration of the Port attribute. Third, through the use of an optional constructor argument. If multiple of these port configuration methods are used, it is up to subclass definition which one takes precedence; in the existing subclasses in this directory, the port value configured in the Local socket address (if a socket address is configured there) will take precedence.

◆ DoDispose()

void ns3::SinkApplication::DoDispose ( )
overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.
