Class Description

This class provides an easy way to get a TCP socket with a connection timeout. The static methods in this class correspond to all of the java.net.Socket constructors. See Sun's documentation for the java.net.Socket class for more information.

Calling getSocketWithTimeout will either return a socket, or will throw an IOException if it times out (because a socket cannot be created). When a new socket is requested with getSocketWithTimeout, the polling interval regulates how often that socket is requested. By default, the polling interval is 100 milliseconds, and can be changed using setPollingInterval. A timeout argument is passed to getSocketWithTimeout, and the socket request times out when a timer that keeps track of the total polling time exceeds the timeout value.

This class only contains static methods. It is never instantiated.
