Class TimerManager<T>

java.lang.Object
  org.glassfish.pfl.tf.timer.spi.TimerManager<T>

public class TimerManager<T>
extends Object

Provides access to timer facilities. This is intended to make it easy to set up timing, either for performance tests, or for adaptive policy management. Note that the constructor and the initialize method must be called from the same thread in order to safely complete the initialization of an instance of this class. After that, multiple threads may access this class for the factory(), points(), and controller() methods.
