      • containsHash

        public boolean containsHash​(byte[] hash)
        Checks whether a PartialHashtree (RFC4998) contains a given hash.
        Parameters:
        hash - the hash to check
        Returns:
        true if the hash is present within the PartialHashtree's set of values, false otherwise.
