Java in a Nutshell, 5th Edition

Name

SocketFactory

Synopsis

This abstract class defines a factory API for creating socket objects. Use the static getDefault( ) method to obtain a default SocketFactory object that is suitable for creating regular java.net.Socket sockets. (This default SocketFactory is the one used by the Socket( ) constructor, which usually provides an easier way to create normal sockets.) Once you have a SocketFactory object, call one of the createSocket( ) methods to create a new socket and optionally connect it to a remote host and optionally bind it to a local address and port. See javax.net.ssl.SSLSocketFactory for a socket factory that can create secure javax.net.ssl.SSLSocket objects.
