        Given a list of elements and a batchSize, this method distributes the elements into batches with the batchSize. Each batch is represented by a List of elements and all the batches are grouped and represented by a List<List> of elements, which is returned by the method.
        Type Parameters:
        T - the type of the draft elements.
        Parameters:
        elements - the list of elements to split into batches.
        batchSize - the size of each batch.
        Returns:
        a list of lists where each list represents a batch of elements.

        Given a reference to a resource of type T, this method checks if the reference id is cached. If it is, then it returns the resource identifier with key. Otherwise, it returns the resource identifier with id. Since, the reference could be null, this method could also return null if the reference id was not in the map.
        Parameters:
        reference - the reference of the resource to check if it's cached.
        referenceIdToKeyCache - the instance that manages cache.
        toResourceIdentifierWithIdAndKey -
        Returns:
        returns the resource identifier with key if the reference id was in cache. Otherwise, it returns the resource identifier with id.

      • isUuid

        public static boolean isUuid​(@Nonnull
                             java.lang.String id)
        Given an id as String, this method checks whether if it is in UUID format or not.
        Parameters:
        id - to check if it is in UUID format.
        Returns:
        true if it is in UUID format, otherwise false.
