Quote: a CLR property is a named value and its methods; typically a getter method and an optional setter method [»hamiJ2_2003]

Quote: inheritance of state allows a parent to share or duplicate its variables with its descendents [»taivA9_1996]

Quote: inheritance by delegation allows changes to a parent node to automatically apply to descendants [»taivA9_1996]

Quote: implement inheritance by delegation or by concatenation; i.e., use reference to share an interface, or use contiguity to copy an interface [»taivA9_1996]

Quote: delegation inheritance shares attributes while embedding inheritance copies attributes; can distinguish in object-based languages but not class-based languages [»abadM_1996]

Note: 'Men are mortal' subordinates the concept 'men' to the concept 'mortal'; not an attribute

Quote: in class-based systems, a class inherits the structure of the parent but not its contents or state

Quote: modify the behavior of an object with traits, dynamic inheritance, or modes; e.g., distinguish open and iconified windows [»taivA9_1996]

Quote: the partially opaque type reveals some of an object's fields in its interface; e.g., used for I/O streams [»nelsG_1991]

Quote: SUIT uses property lists to store information about an object; also searches the object's class and a global property list [»pausR10_1992]

Quote: SUIT property editor displays object, class and global property lists; drag-and-drop; makes it easy to learn state inheritance [»pausR10_1992]

Quote: for locating properties of composite objects, SUIT checks the composition tree without checking their class properties [»pausR10_1992]

Quote: Self parent slots are marked by '*' and searched if message not found

Quote: selective inheritance blurs the distinction between parents and methods; i.e., a descendant can use a subset of a parent's identifiers as its own [»taivA9_1996]

Quote: a mixin class implements properties solely for use in other classes; create a new class by combining mixins [»taivA9_1996]

Quote: representation inheritance is white-box inheritance that conforms to representation invariants and abstraction relations [»edwaSH2_1997]

Quote: use representation inheritance for efficient implementation of new operations; e.g., swap the tails of two lists without cross links or missed elements [»edwaSH2_1997]

Quote: every class should include a method to test its representation invariant; use to test and stress test representation inheritance [»edwaSH2_1997]

Quote: most object-oriented languages allow subclasses to use implementation details of a superclass; limited encapsulation [»liskB_1996]

Quote: with white box inheritance, need to retest all inherited methods and all superclasses [»edwaSH2_1997]

Quote: with representation inheritance, do not need to retest the superclass; as long as its representation invariant and abstraction relation are correctly maintained

Quote: while dogs inherit characteristics from mammals, the definition of mammals is partly from dogs [»coxBJ7_1983]

Quote: the is-a relation does not hold for particular instances of squares and rectangles; e.g. a rectangle of height 5 and width 20 [»winkJF8_1992]

Quote: with cancellation, Clyde the elephant could be just about anything, including a giraffe; the Elephant node is just a collection of properties [»bracRJ10_1983]
