      • getRatingRollup

        public java.io.Serializable getRatingRollup​(org.alfresco.service.cmr.repository.NodeRef targetNode,
                                            java.lang.String ratingSchemeName,
                                            java.lang.String ratingRollupName)
        Description copied from interface: RatingService
        This method returns a 'rolled up' property value for the specified targetNode. Examples of rolled up property values are 'ratingTotal', 'ratingCount', but other values can be added.

        Rolled up properties in the RatingService are stored as properties on the rated node and have their values calculated by running a fixed algorithm on properties stored across the cm:rating child nodes. An example of such a roll up would be 'ratingTotal' which would be the sum of all ratings applied to the targetNode in the specified rating scheme.

        By rolling up property values from the various cm:rating child nodes and persisting them as individual properties on the cm:rateable node itself, we are able to support indexing, searching and sorting of such properties.

        Specified by:
        getRatingRollup in interface RatingService
        Parameters:
        targetNode - the rated node whose rolled up property we wish to read.
        ratingSchemeName - the rating scheme name in which the property is relevant.
        ratingRollupName - the name of the rating rollup property, as given in AbstractRatingRollupAlgorithm.getRollupName().
        Returns:
        A value for the rolled up property, which will depend of course on the rollup requested.
