      • contributionUpdated

        public void contributionUpdated​(String id,
                                        RenderView contrib,
                                        RenderView newOrigContrib)
        Description copied from class: ContributionFragmentRegistry
        Adds or updates a contribution.

        If the contribution doesn't yet exists then it will be added, otherwise the value will be updated. If the given value is null the existing contribution must be removed.

        The second parameter is the contribution that should be updated when merging, as well as stored and used. This usually represents a clone of the original contribution or a merge of multiple contribution fragments. Modifications on this object at application level will be lost on next method call on the same object id: modifications should be done in the ContributionFragmentRegistry.merge(Object, Object) method.

        The last parameter is the new contribution object, unchanged (original) which was neither cloned nor merged. This object should never be modified at application level, because it will be used each time a subsequent merge is done. Also, it never should be stored.
