        Creates a RRA with a single data source.
        Specified by:
        createSingleRRA in class AbstractRRA
        Parameters:
        dsIndex - the RRA-DS index

        java.lang.IllegalArgumentException - the illegal argument exception

      • formatMergeable

        public boolean formatMergeable​(AbstractRRA sourceRra)
        Description copied from class: AbstractRRA
        Format mergeable.

        Two RRA can be merged if and only if the Consolidation Function and the PDP per row are the same.

        The amount of rows is not strict for a merge operation.

        • If the sourceRra has more rows than the current RRA, the result will be truncated by the number of rows on the current RRA.
        • If the sourceRra has less rows than the current RRA, the result will have a NaN window as big as the different between the number of rows.
        Specified by:
        formatMergeable in class AbstractRRA
        Parameters:
        sourceRra - the source RRA object
        Returns:
        true, if the format is mergeable

      • hasAverageAsCF

        public boolean hasAverageAsCF()
        Description copied from class: AbstractRRA
        Checks for average as consolidation function.
        Specified by:
        hasAverageAsCF in class AbstractRRA
        Returns:
        true, if the consolidation function is AVERAGE
