      • store

        public void store​(ImageModel imageModel)
        Description copied from class: ImageModelCache
        Adds an ImageModel to the cache. The image is always added only in the local cache. Remote caches will pull the images they lack on demand.
        Specified by:
        store in class ImageModelCache
        Parameters:
        imageModel - the ImageModel to add

      • update

        public void update​(ImageModel imageModel)
        Description copied from class: ImageModelCache
        Updates an ImageModel in the cache. This means that all remote copies of this image will be invalidated. TODO: should investigate more complex cases. Maybe the remote workers still want to work with a remote snapshot. Include versioning instead of invalidating?
        Specified by:
        update in class ImageModelCache
        Parameters:
        imageModel - the ImageModel to update
