        Overrides:
        hashCode in class java.lang.Object
        Implementation Specification:
        This version returns the hash code of the decorated object if there is one; otherwise this method delegates to the parent class.

        public boolean equals​(java.lang.Object object)
        Overrides:
        equals in class java.lang.Object
        Implementation Specification:
        This version considers the given object equal to this object if it is of the same type as this object, and this object's decorated object's Object.equals(Object) method also returns true for the objects's decorated object or both decorated objects are null.

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
        Implementation Specification:
