Constructor Detail

ConcurrentGCEvent

public ConcurrentGCEvent()

Method Detail

getDuration

public double getDuration()

Time this step in the concurrent GC mechanism took.

[CMS-concurrent-sweep: 0.005/<em>0.015</em> secs]

So in this example the time that was exclusively spent on the step would be 0.005secs of an overall duration of 0.015secs.

So AbstractGCEvent.getPause() returns the time that was exclusively spent.

Returns:

time a certain concurrent GC step took.

cloneAndMerge

public ConcurrentGCEvent cloneAndMerge(AbstractGCEvent<ConcurrentGCEvent> otherEvent)

Overrides:

cloneAndMerge in class AbstractGCEvent<ConcurrentGCEvent>

setDuration

public void setDuration(double duration)

Set duration.

Parameters:

duration - time spent in gc mechanism

equals
