Class NetworkPortAssigner

java.lang.Object

test.tck.msgflow.callflows.NetworkPortAssigner

public class NetworkPortAssigner
extends Object

Allows integration tests to be run in parallel by assigning a free port. A port range will be assigned based in JVM PID, and a circular sequence around this range will be provided. JVM PID are expected to be sequenced, so incremental PID will be received. It is assumed that low number of forked JMVs will be used to run parallel tests ( near cores in system), so the PORT_RANGE dont provide much collisions.
