Parameterized Inheritance vs. Multiple Inheritance

Amit Patel, Vitaly Shmatikov, John Mitchell · 2007

In this paper, we demonstrate that multiple inheritance can be expressed as a combination of single inheritance, parameterization, and interface subtyping. We propose a language construct called "phunctor" as an alternative to multiple inheritance. Phunctors combine single inheritance and constrained parameterization to provide required functionality in the contexts where multiple inheritance is used, while retaining the benefits of static type checking. We argue that using parameterized inheritance instead of multiple inheritance leads to more robust class hierarchy designs. We discuss how phunctors can be implemented efficiently and show that phunctors facilitate several common design patterns.

Safe Dynamic Multiple Inheritance Safe Dynamic Multiple Inheritance

Ny Munkegade, Erik Ernst, Erik Ernst · 2002

Abstract. Combination of descriptive entities—i.e. multiple inheritance and related mechanisms—is usually only supported at compile time in statically typed languages. The language gbeta is statically typed and has supported run-time creation of classes and methods since 1997, by means of the pattern combination operator ‘&’. However, with certain combinations of operands the ‘& ’ operator fails; as a result, creation of new classes and methods at run-time had to be considered a dangerous operation. This paper presents a large and useful class of combinations, and proves that combinations in this class will always succeed. 1

Analysis of inheritance and multiple inheritance

CP Willis · Software Engineering Journal · 1996

Some of the more common descriptions of inheritance, and particularly multiple inheritance are analysed; these are frequently unclear and even contradictory in much of the published literature. Using abstract data types to provide examples, it is shown how a consistent basis for inheritance and multiple inheritance may be built up, which helps to clarify the true meaning of inheritance.

Selective multiple inheritance

Dov Dori, Erez Tatcher · IEEE Software · 1994

In conventional multiple inheritance, a class must inherit features from all its ancestors. With this proposed generalized method, you can use an embryonic class, in which the classes themselves are instances, to select ancestor subsets without creating a combinatorial explosion in the object diagram.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Multiple inheritance systems

Eva Jablonka, Marion J. Lamb · 1995

Abstract In 1958, the centenary of the first publication of Darwin and Wallace’s theory of evolution by natural selection, Donald Michie expressed the opinion that the ‘third stage’ in genetics had arrived. The first stage was that of classical Mendelian genetics, dominated by Johannsen’s genotype concept and the chromosomal theory. The second stage, which began in the post-war period, was the incorporation of the inheritance of cytoplasmic factors into genetics; it was recognized that there are cytoplasmic inheritance systems which can transmit epigenetic information germinally. The third stage, which, according to Michie, was just dawning in 1958, was a synthesis of these two: the acceptance that DNA and the cytoplasm are not independent, and that there are persistent interactions between them (Fig. 10.1).

Modular multiple dispatch with multiple inheritance

Eric E. Allen, Joseph J. Hallett, Victor Luchangco et al. · 2007

Overloaded functions and methods with multiple dispatch are useful for extending the functionality of existing classes in an object-oriented language. However, such functions introduce the possibility of ambiguous calls that cannot be resolved at run time, and modular static checking that such ambiguity does not exist has proved elusive in the presence of multiple implementation inheritance. We present a core language for defining overloaded functions and methods that supports multiple dispatch and multiple inheritance, together with a set of restrictions on these definitions that can be statically and modularly checked. We have proved that these restrictions guarantee that no undefined nor ambiguous calls occur at run time, while still permitting various kinds of overloading.

Safe Dynamic Multiple Inheritance

Combination of descriptive entities--i.e. multiple inheritance and related mechanisms--is usually only supported at compile time in statically typed languages. The language gbeta is statically typed and has supported run-time creation of classes and methods since 1997, by means of the pattern combination operator '&amp;amp;'. However, with certain combinations of operands the '&amp;amp;' operator fails; as a result, creation of new classes and methods at run-time had to be considered a dangerous operation.

Inheritance of Multiple Traits

Stevan J. Arnold · 2023

Abstract The G-matrix provides a useful way to model inheritance when multiple traits are affected by many genes and genetically coupled. The G-matrix is an m trait × m trait table with genetic variances on its main diagonal and genetic covariances elsewhere. The genetic covariance between two traits summarizes genetic connections arising from linkage disequilibrium and/or pleiotropy. Studies of multiple trait inheritance often reveal appreciable genetic correlations between traits, especially when those traits are size-related. The M-matrix summarizes the patterns of mutational effects on multiple traits. Just as covariances among relatives are the foundation for estimation of the G-matrix, the accumulation of mutations in inbred lines is the foundation for estimation of the M-matrix. Studies of G- and M-matrices suggest that these matrices have almost as many dimensions of variation as the number of characters included in the study. Consequently, these matrices are unlikely to constrain the course of evolution on long evolutionary timescales. The entire G-matrix, as well as its constituent genetic variances and covariances, can be visualized as achieving a stable balance between opposing forces. This stable equilibrium represents a compromise between alternative structures imposed by the processes of selection, mutation, recombination, and migration.

MULTIPLE INHERITANCE UNTUK C++

Khoerul Anwar · Jurnal Teknologi Informasi · 2011

Multiple inheritance is the ability of the class to provide more of a super class. Multiple inheritance in a programming language to support a program to be structured as a collection of inheritance lattice of a collection of inheritance tree. Multiple inheritance recognized to be an important structuring tool. It is as well as the recognition that multiple inheritance is a fairly difficult / complex in a programming language, is difficult to implement, and costly to run. Here the authors will try to explain that none of the three estimates are true. Keywords: Multiple Inheritance, Super Class

Multiple Inheritance Linearization f

R. Ducournau, M. Habib, M. Huchard et al. · 2008

Previous studies concerning multiple inheritance convinced us that a better analysis of conflict res-olution mechanisms was necessary. In [DHHM92], we stated properties that a sound mechanism has to respect. Among them, a monotonicity princi-ple plays a critical role, ensuring that the inher-itance mechanism behaves “naturally ” relative to the incremental design of the inheritance hierar-chy. We focus here on linearizations and present an intrinsically monotonic linearization, whereas currently used linearizations are not. This paper describes the algorithm in detail, explains the de-sign choices, and compares it to other lineariza-tions, with LOOPS and CLOS taken as references. In particular, this new linearization extends CLOS and LOOPS linearizations, producing the same re-sults when these linearizations are sound. tPlease send correspondence concerning this paper to M.

Multiple factors in mendelian inheritance

E. C. MacDowell · Journal of Experimental Zoology · 1914

Since cases of simple Mendelian phenomena have been very frequently described, the interest of the student of genetics has shifted from the attempt to prove, or disprove, Mendelism towards the investigation of the extent of the application of Mendel's fundamental principles.Perhaps this is why the apparent exclusion of anything Mendelian from size inheritance by Castle's work on the ear length of rabbits, aroused so much interest.Castle ('09) found that the ear lengths of rabbit offspring were in general'intermediate in relation to the parents.This seemed to indicate a simple blending inheritance in which the size-controlliig elements from either parent were permanently joined in the offspring, never to segregate.Yet in the same rabbits Mendelian ratios were being given and segregation was taking place in the color of the hair.The appearance of a paper by H.Nilsson-Ehle ('09) brought a new possible interpretation of the ear length crosses.In this paper evidence was presented to show that there may be two or more Mendelian factors for the same character, which factors develop the character whether they appear alone or in any combination with the others.Nilsson-Ehle found in certain crosses of oats and wheat in which the colors of the glumes and seeds were considered, that simple Mendelian ratios (3 : 1) were generally given, but in cer-This paper is based on an investigation carried on in the Laboratory of Genetics of the Bussey

Multiple inheritance and constructional change

Graeme Trousdale · Benjamins current topics · 2015

Language as a network of dependencies or constructions is a central feature of many cognitive theories of grammar. In this network, inheritance relationships are used to describe synchronic facts about a language whereby members of a less abstract set inherit properties from a more general set, and in the case of multiple inheritance, from more than one general set. This article explores some of the ways in which the language network may change over time, particularly the ways in which more than one constructional type may be considered to be the source of a change in the network.
