Interface ContributionModification

  • All Known Implementing Classes:
    ContributionReminderListener, ContributionTrackingService
    public interface ContributionModification
    It is a process implied within the modification of a contribution. Usually such process is about the modification of some transverses resources that are used by the contribution being modified such as reminders for example. The process should be invoked only when one or more contributions are modified, not when a component instance is modified with its whole contributions.

    Each implementation of this interface is invoked by the generic contribution modification process to perform their specific task. The process listens for events about contribution modification and so each more concrete business service has to send such events once the contribution of which they are in charge is modified. Usually, this interface should be implemented by each transverse services in Silverpeas Core.

    For each contribution, whatever it is, different kind of transverses resources can be created and managed. When such a contribution is then modified in Silverpeas, it is necessary to clean up also those resources. Nevertheless, both the generic contribution modification process and the contribution itself aren't usually aware of them. It is then the responsibility of the services behind the different kinds of resources to take in charge the freed of the resources related to the contribution being modified. For doing, they have to implement this interface.

      • update

        void update​(Contribution before,
            Contribution after)
        Updates the resources belonging to the specified contribution. This method is invoked by the generic contribution modification service when an event about the modification of a contribution is received.
        Parameters:
        before - the contribution before the modification.
        after - the contribution after the modification.
