Class ServiceInvocationContext

java.lang.Object

jadex.bridge.service.component.ServiceInvocationContext

public class ServiceInvocationContext
extends java.lang.Object

Context for service invocations. Contains all method call information. Invariants that must hold before, during and after a service call for the NEXT/CUR/LAST service calls caller callee before next = null || user defined cur = actual call during next = null (set in ServiceInvocContext) cur = next cur = cur (same as in before) (set in MethodInvocationInterceptor) after next = null cur = cur (same as in before) last = next (set in MethodInvocationInterceptor)
