Method Detail

getFileLockingPortChooser

public static LockingPortChooser getFileLockingPortChooser()

Returns a LockingPortChooser that works by acquiring a lock for a port by creating a FileLock on the corresponding byte in an agreed upon file. The FileLocks are created by GlobalFilePortLocker. Because FileLocks are held by the whole JVM, we also need a system of locking within this JVM, which is handled by the LocalPortLocker. In the SocketPortLocker, we also check that the socket is available.

Returns:

the LockingPortChooser that can generate ports that should be free to use as long as the lock is held
