public class WrappingTaskMonitor extends java.lang.Object implements TaskMonitor
An implementation of theTaskMonitor
interface that simply wraps a delegate task monitor. This is useful for classes that wish to wrap a task monitor, changing behavior as needed by overriding a subset of methods.Synchronization Policy:
We wish for this class to be performant. Thus, we do not synchronize the methods of this class. ThesetDelegate(TaskMonitor)
is synchronized to ensure thread visibility for the state of the delegate monitor.When calling
setDelegate(TaskMonitor)
there is the potential for the values being transferred to become inconsistent with any new values being set. We have decided that this does not much matter for the overall progress or the messages on the monitor. However, most of the other setter methods could lead to bad behavior if they are inconsistent.
