A specific exception type and its subclasses can be selected for exception events. Caught exceptions, uncaught exceptions, or both can be selected.

MonitorContendedEnterRequest createMonitorContendedEnterRequest()

Creates a new disabled MonitorContendedEnterRequest. The new event request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request. Not all target virtual machines support this operation. Use VirtualMachine.canRequestMonitorEvents() to determine if the operation is supported.

MonitorContendedEnteredRequest createMonitorContendedEnteredRequest()

Creates a new disabled MonitorContendedEnteredRequest. The new event request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request. Not all target virtual machines support this operation. Use VirtualMachine.canRequestMonitorEvents() to determine if the operation is supported.

MonitorWaitRequest createMonitorWaitRequest()

Creates a new disabled MonitorWaitRequest. The new event request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request. Not all target virtual machines support this operation. Use VirtualMachine.canRequestMonitorEvents() to determine if the operation is supported.

MonitorWaitedRequest createMonitorWaitedRequest()

Creates a new disabled MonitorWaitedRequest. The new event request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request. Not all target virtual machines support this operation. Use VirtualMachine.canRequestMonitorEvents() to determine if the operation is supported.

StepRequest createStepRequest(ThreadReference thread, int size, int depth)

Creates a new disabled StepRequest. The new event request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request.

The returned request will control stepping only in the specified thread; all other threads will be unaffected. A size value of StepRequest.STEP_MIN will generate a step event each time the code index changes. It represents the smallest step size available and often maps to the instruction level. A size value of StepRequest.STEP_LINE will generate a step event each time the source line changes unless line number information is not available, in which case a STEP_MIN will be done instead. For example, no line number information is available during the execution of a method that has been rendered obsolete by by a VirtualMachine.redefineClasses(java.util.Map<? extends com.sun.jdi.ReferenceType, byte[]>) operation. A depth value of StepRequest.STEP_INTO will generate step events in any called methods. A depth value of StepRequest.STEP_OVER restricts step events to the current frame or caller frames. A depth value of StepRequest.STEP_OUT restricts step events to caller frames only. All depth restrictions are relative to the call stack immediately before the step takes place.

Only one pending step request is allowed per thread.

Note that a typical debugger will want to cancel stepping after the first step is detected. Thus a next line method would do the following:

     EventRequestManager mgr = myVM.{@link VirtualMachine#eventRequestManager eventRequestManager}();
     StepRequest request = mgr.createStepRequest(myThread,
                                                 StepRequest.{@link StepRequest#STEP_LINE STEP_LINE},
                                                 StepRequest.{@link StepRequest#STEP_OVER STEP_OVER});
     request.{@link EventRequest#addCountFilter addCountFilter}(1);  // next step only
     request.enable();
     myVM.{@link VirtualMachine#resume resume}();
 

BreakpointRequest createBreakpointRequest(Location location)

Creates a new disabled BreakpointRequest. The given Location must have a valid (that is, non-negative) code index. The new breakpoint is added to the list managed by this EventRequestManager. Multiple breakpoints at the same location are permitted. Use EventRequest.enable() to activate this event request.

AccessWatchpointRequest createAccessWatchpointRequest(Field field)

Creates a new disabled watchpoint which watches accesses to the specified field. The new watchpoint is added to the list managed by this EventRequestManager. Multiple watchpoints on the same field are permitted. Use EventRequest.enable() to activate this event request.

Not all target virtual machines support this operation. Use VirtualMachine.canWatchFieldAccess() to determine if the operation is supported.

ModificationWatchpointRequest createModificationWatchpointRequest(Field field)

Creates a new disabled watchpoint which watches accesses to the specified field. The new watchpoint is added to the list managed by this EventRequestManager. Multiple watchpoints on the same field are permitted. Use EventRequest.enable() to activate this event request.

Not all target virtual machines support this operation. Use VirtualMachine.canWatchFieldModification() to determine if the operation is supported.

VMDeathRequest createVMDeathRequest()

Creates a new disabled VMDeathRequest. The new request is added to the list managed by this EventRequestManager. Use EventRequest.enable() to activate this event request.

This request (if enabled) will cause a VMDeathEvent to be sent on termination of the target VM.

A VMDeathRequest with a suspend policy of SUSPEND_ALL can be used to assure processing of incoming SUSPEND_NONE or SUSPEND_EVENT_THREAD events before VM death. If all event processing is being done in the same thread as event sets are being read, enabling the request is all that is needed since the VM will be suspended until the EventSet containing the VMDeathEvent is resumed.

Not all target virtual machines support this operation. Use VirtualMachine.canRequestVMDeathEvent() to determine if the operation is supported.

void deleteEventRequest(EventRequest eventRequest)

Removes an eventRequest. The eventRequest is disabled and the removed from the requests managed by this EventRequestManager. Once the eventRequest is deleted, no operations (for example, EventRequest.setEnabled(boolean)) are permitted - attempts to do so will generally cause an InvalidRequestStateException. No other eventRequests are effected.

Because this method changes the underlying lists of event requests, attempting to directly delete from a list returned by a request accessor (e.g. below):

   Iterator iter = requestManager.stepRequests().iterator();
   while (iter.hasNext()) {
      requestManager.deleteEventRequest(iter.next());
  }
 

may cause a ConcurrentModificationException. Instead use deleteEventRequests(List) or copy the list before iterating.

void deleteEventRequests(List<? extends EventRequest> eventRequests)

Removes a list of EventRequests.

void deleteAllBreakpoints()

Remove all breakpoints managed by this EventRequestManager.
