        public static <T extends EppResourceVKey<T> createEppVKeyFromString​(java.lang.String keyString)
        Constructs a VKey for an EppResource from the string representation.

        The string representation is obtained from the stringify() function and like this: kind:TestObject@sql:rO0ABXQAA2Zvbw

      • getKind

        public java.lang.Class<? extends T> getKind()
        Returns the type of the entity.
