com.espertech.esper.core.service.EPStatementHandleCallback
Statement resource handle and callback for use with {@link com.espertech.esper.filter.FilterService} and{@link com.espertech.esper.schedule.SchedulingService}.
Links the statement handle identifying a statement and containing the statement resource lock, with the actual callback to invoke for a statement together.
