public interface EventSet
Several Event objects may be created at a given time by
the target VirtualMachine. For example, there may be
more than one BreakpointRequest
for a given Location
or you might single step to the same location as a
BreakpointRequest. These Event objects are delivered
together as an EventSet. For uniformity, an EventSet is always used
to deliver Event objects. EventSets are delivered by
the EventQueue.
EventSets are unmodifiable.
Associated with the issuance of an event set, suspensions may
have occurred in the target VM. These suspensions correspond
with the suspend policy.
To assure matching resumes occur, it is recommended,
where possible,
to complete the processing of an event set with
EventSet.resume().
The events that are grouped in an EventSet are restricted in the following ways:
Event,

resume()
Resumes threads suspended by this event set. |

int suspendPolicy()
EventRequest for the possible
policy values.
In rare cases, the suspend policy may differ from the requested
value if a ClassPrepareEvent has occurred in a
debugger system thread. See ClassPrepareEvent.thread()
for details.
SUSPEND_ALL,
SUSPEND_EVENT_THREAD or
SUSPEND_NONE.EventIterator eventIterator()
Event objects.
void resume()
suspendPolicy()
is EventRequest.SUSPEND_ALL, a call
to this method is equivalent to
VirtualMachine.resume(). If the
suspend policy is
EventRequest.SUSPEND_EVENT_THREAD,
a call to this method is equivalent to
ThreadReference.resume() for the event thread.
Otherwise, a call to this method is a no-op.
