Examples of com.sun.jdi.request.BreakpointRequest

com.sun.jdi.request.BreakpointRequest
Identifies a {@link Location} in the target VM at whichexecution should be stopped. When an enabled BreakpointRequest is satisfied, an {@link com.sun.jdi.event.EventSet event set} containing an{@link com.sun.jdi.event.BreakpointEvent BreakpointEvent}will be placed on the {@link com.sun.jdi.event.EventQueue EventQueue} andthe application is interrupted. The collection of existing breakpoints is managed by the {@link EventRequestManager} @see Location @see com.sun.jdi.event.BreakpointEvent @see com.sun.jdi.event.EventQueue @see EventRequestManager @author Robert Field @since 1.3
