A MONOTONIC SUPERCLASS LINEARIZATION FOR DYLAN PDF
A Monotonic Superclass Linearization for Dylan. Kim Barrett . Bob Cassels [email protected]>. Paul Haahr. In computing, the C3 superclass linearization is an algorithm used primarily to obtain the order It was first published at the OOPSLA conference, in a paper entitled “A Monotonic Superclass Linearization for Dylan”. It was adapted to the. The C3 superclass linearization algorithm is more intuitive and allows for greater monotonicity of method orderings, a consistent superclass linearization.

C3 exists on CPAN.
Roland Ducournau 9 Estimated H-index: April Learn how and when to remove this template message. Retrieved 18 January Retrieved August 14, We present an implementation based on merging and a survey of class heterarchies from several large programs, analyzing where commonly superdlass linearizations differ.
The Dylan superclass linearization is sometimes counter-intuitive. Gregor Kiczales 39 Estimated H-index: Recent work has defined several desirable characteristics for linearizations, the most important being monotonicity, which prohibits inherited properties from skipping over direct superclasses.
Linearizzation is also available as an alternative, non-default MRO in the core of Perl 5 starting with version 5. Ref Source Add To Collection.
This page was last edited on 28 Aprilat The Dylan linearization is monotonic, easily described, strictly observes local precedence order, and produces the same ordering as CLOS when that is monotonic. Preserving and reusing intermediate data.
Steele 1 Estimated H-index: The list of parents as the last argument to the merge process preserves the local precedence order of direct parent classes. View in Source Cite this paper.
The name C3 refers to the three important properties of the resulting linearization: Moon, Keith Playford, P. However, this will result in an infinitely looping recursion in the presence of a cyclic class hierarchy. The selected element is removed from all linearizatikn lists where it appears as a head and appended to the output list. The latter does not alter behaviour post. Moon and Keith Playford and P.

Abstract Object-oriented languages with multiple inheritance and automatic conflict resolution typically use a linearization of superclasses to determine which version of a property to inherit when several superclasses provide definitions. Roland Ducournau 4 Estimated H-index: Level-based data sharing for digital content production. To fix that, the C3 linearization was developed.
Combined with Dylan’s sealing mechanism, a monotonic linearization enables some compile-time method selection that would otherwise be impossible in the absence of a closed-world assumption. Wikipedia articles needing clarification from April All Wikipedia articles needing clarification.
The name “C3” is not an initialism. Smyth 2 Estimated H-index: Note, that a good head may appear as the first element in multiple lists at the same time, but it is forbidden to appear anywhere else. Experiments show that there are some differences in existing code; we found so far three, two of them in duim-gadgets, one in winduim. Moon, Keith Playford, and P. The art of metaobject protocol.
