This package defines JDI events and event processing. An {@link com.sun.jdi.event.Event} is always a member of an {@link com.sun.jdi.event.EventSet}, which is retrieved from the {@link com.sun.jdi.event.EventQueue}. Examples of Events include {@link com.sun.jdi.event.BreakpointEvent "breakpoints events"}, {@link com.sun.jdi.event.ThreadStartEvent "thread creation events"} and {@link com.sun.jdi.event.VMDeathEvent "virtual machine death event"}. With the exception of termination events, all events received must be requested with an {@link com.sun.jdi.request.EventRequest "EventRequest"}. The {@link com.sun.jdi.request} package defines event requests and event request management.

Methods may be added to the interfaces in the JDI packages in future releases. Existing packages may be renamed if the JDI becomes a standard extension.
