Class LockManager

    java.lang.Object
      kieker.webgui.service.impl.utility.LockManager

    public final class LockManager

extends Object

This manager is responsible for locking critical code using keys. Internally we use `ReentrantLock`s, but make sure that they are removed once they are no longer needed. The manager has been developed with a simple design. If necessary, the manager can be modified in order to provide a faster access to the locks.
