Interface BreakpointRequest

All Superinterfaces:

EventRequest, Locatable, Mirror

@Exported
public interface BreakpointRequest
extends EventRequest, Locatable

Identifies a Location in the target VM at which execution should be stopped. When an enabled BreakpointRequest is satisfied, an event set containing an BreakpointEvent will be placed on the EventQueue and the application is interrupted. The collection of existing breakpoints is managed by the EventRequestManager
