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.

Moon, Keith Playford, and P. The Art of the Metaobject Protocol. The name C3 refers to the three important properties of the resulting linearization: Steele 1 Estimated H-index: Ref Source Superclase To Collection.
In computingthe C3 superclass linearization is an algorithm used primarily to obtain the order in which methods should be inherited the “linearization” in the presence of multiple inheritanceand is often termed Method Resolution Order MRO.
Robert Giles Wilson 1 Estimated H-index: Retrieved from ” https: Bertrand Meyer 38 Estimated H-index: A superclass linearization also known as a class precedence list is used for resolving conflicts among multiply-inherited superclasses which provide differing definitions of the same method. Proposal for a monotonic multiple inheritance linearization. Are you looking for Sebastian Wrede 15 Estimated H-index: Look-based selection for rendering a computer-generated animation.
After the C3 linearization was proposed init was subsequently adapted in Python 2. Roland Ducournau 9 Estimated H-index: Tucker Withington in a paper html version. The name “C3” is not an linearizafion.
Moon 4 Estimated H-index: Advanced Search Include Citations. If at some point no good head can be selected, because the heads of all remaining lists appear in any one tail of the lists, then the merge is impossible to compute due to inconsistent orderings of dependencies in the inheritance hierarchy and no linearization of the original class exists.
The pull request was finally merged into master. Smyth 1 Estimated H-index: Cited Source Add To Collection. Advanced Search Include Citations Disambiguate. The list of parents as the last argument to the merge process pinearization the local precedence order of direct parent classes.
The C3 linearization has been around for a long time, does not break any existing code, and is commonly agreed upon as being the right thing to do in mailing list discussions. Recent work has defined several desirable characteristics for linearizations, the most important being monotonicity, which prohibits inherited properties from skipping over direct superclasses.
Peter Mcnerney 2 Estimated H-index: The latter does not alter behaviour post. In order to allow for more optimizations, especially compression of dispatch tables, which requires monotonicity of method orderings, a consistent superclass linearization algorithm is needed.

A naive divide and conquer approach to computing the linearization of a class may invoke monootonic algorithm recursively to find the linearizations of parent classes for the merge-subroutine.
The process of selecting and removing a good head to extend the output list is repeated until all remaining lists are exhausted.
From Wikipedia, the free encyclopedia. This article may be confusing or unclear to readers. Note, that a good head may appear as the first element in multiple lists at the same time, but it is forbidden to fpr anywhere else. 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.
The selected element is removed from all the lists where it appears as a head and appended to the output list. Experiments show that there are some differences in existing code; we found so far three, two of them in duim-gadgets, one in winduim.

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.
