org.apache.isis.applib.services.background.ActionInvocationMemento

A memento for an action invocation, to allow the details of an action invocation to be captured and stored, then executed later.

Provided as a mechanism by which implementations of {@link BackgroundService} can hand-off work to the {@link BackgroundCommandService} through {@link BackgroundCommandService#execute(ActionInvocationMemento)}. This is used by the default implementation of BackgroundServiceDefault in Isis' core-runtime.

Implementation-wise this is a wrapper around {@link MementoService.Memento}, and abstracts away the details of the keys used to store the various pieces of information stored in the underlying memento.


    /**
     * Not API
     */
    ActionInvocationMemento newActionInvocationMemento(String mementoStr) {
        return new ActionInvocationMemento(mementoService, mementoStr);
    }


                    command.setStartedAt(Clock.getTimeAsJavaSqlTimestamp());
                    command.setExecutor(Executor.BACKGROUND);


                    final String memento = command.getMemento();
                    final ActionInvocationMemento aim = new ActionInvocationMemento(mementoService, memento);


                    final String actionId = aim.getActionId();


                    final Bookmark targetBookmark = aim.getTarget();
                    final Object targetObject = bookmarkService.lookup(targetBookmark);


                    final ObjectAdapter targetAdapter = adapterFor(targetObject);
                    final ObjectSpecification specification = targetAdapter.getSpecification();
