abstract ;;Quote: although inheritance is central to object-oriented programming, researchers rarely agree on its meaning and usage

439 ;;Quote: inheritance allows the creation of a new class from existing classes; i.e., incremental program development

440 ;;Quote: inheritance is record combination; the record for a new class is like its parent's record, but extended with new properties

441 ;;Quote: object-oriented programming originated from Simula for modeling the concepts of an application domain

441+;;Quote: inheritance represents conceptual specialization of a model

441 ;;Quote: object-oriented programming directly supports abstraction by classification/instantiation, aggregation/decomposition, generalization/specialization, grouping/individualization

442 ;;Quote: object-oriented languages support aggregation/decomposition by using an object as a variable of another object

442 ;;Quote: object-oriented programming supports grouping/individualization by defining arbitrary collection classes such as lists and dictionaries

447 ;;Quote: the use of inheritance for conceptual specialization is rarely realized

452 ;;Quote: without late binding, newly defined components may not work with inherited operations; needed for incremental development

455 ;;Quote: inheritance with late binding, self-reference, and super-reference allows objects to be reused without textual copying or editing; a new way to write programs

455+;;Quote: late binding and self-reference allow a programmer to change object behavior without access to its representation

455+;;Quote: super-reference allows access to redefined properties without code duplication

459 ;;Quote: within computer memory, only reference and contiguity can express direct relationships

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

461 ;;Quote: inheritance by delegation allows changes to a parent node to automatically apply to descendants

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

468 ;;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

469 ;;Quote: a mixin class implements properties solely for use in other classes; create a new class by combining mixins

471 ;;Quote: inheritance is synonymous with receiving; the parent and descendent share something with each other

741 ;;Quote: in object-oriented programs, inheritance means that the same compiled code is shared by descendents

472 ;;Quote: inheritance of state allows a parent to share or duplicate its variables with its descendents

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

472 ;;Quote: most object-oriented systems use single dispatching; i.e., a message is sent to one object; e.g., "5+4" is 5.plus(4)

472+;;Quote: single dispatching does not match binary operations; e.g., possible code duplication for mixed integer and floating point arithmetic

473 ;;Quote: single dispatching encourages the definition of abstract data types; multiple dispatching does not

474 ;;Quote: object-oriented inheritance allows the extension and refinement of existing code without modifying the code. This is the essence of inheritance
