org.e2etrace.timer
Class DefaultTimerFactory

java.lang.Object
  org.e2etrace.timer.DefaultTimerFactory

All Implemented Interfaces:

ITimerFactory

public class DefaultTimerFactory
extends Object
implements ITimerFactory

Default Factory class for Timer instances.

The factory returns a new Timer instance. In the default configuration, the new Timer is of the type DefaultTimer. Please refer to the documentation of this class to learn about the restrictions of the underlying implementation.

However, if e2etrace has been compiled and is executed using JDK 5.0 (or higher), the factory will return instances of the type ExactTimer. This Timer implementation uses the advanced timing features of the new JDK releases and avoids all problems described in the documentation of DefaultTimer.

Please note the different constructors of the factory. You can force the factory to create specific types of Timers by using the appropriate constructor. If you use the default constructor, the above described logic applies.

You can use the class PrintTimerAccuracy to determine which Timer type will be used by e2etrace on your system and which accuracy the Timers are able to deliver.
