Examples of fr.imag.adele.apam.declarations.instrumentation.CallbackDeclaration

fr.imag.adele.apam.declarations.instrumentation.CallbackDeclaration
The declaration of a method that needs to be invoked on the implementation to notify an APAM event (component and dependencies lifecycle). Currently all the supported callbacks take a single parameter of type fr.imag.adele.apam.Component. TODO currently we also allow to disable parameter validation to allow injecting service objects for dependencies. However we should be more precise on the type of the parameters.

    /*
     * Add automatically a life-cycle callback in case the class implements directly the APAM component interface
     */
    Class<?> pojoClass = this.getClazz();
    if (ApamComponent.class.isAssignableFrom(pojoClass)) {
      implementation.addCallback(AtomicImplementationDeclaration.Event.INIT,    new CallbackDeclaration(implementation, "apamInit"));
      implementation.addCallback(AtomicImplementationDeclaration.Event.REMOVE, new CallbackDeclaration(implementation, "apamRemove"));
    }
    
    /*
     * register callbacks
