Class AvailableSocketPorts

java.lang.Object

org.springframework.xd.test.fixtures.util.AvailableSocketPorts

public class AvailableSocketPorts
extends java.lang.Object

Utility class to find available server ports.

Leverages SocketUtils.findAvailableServerSocket(int) but in addition remembers the allocated ports. This is because the port may not be used immediately after it is found and thus may be re-allocated on subsequent calls.
