Combining Inclusion Polymorphism and Parametric Polymorphism [article]

Sabine Glesner, Karl Stroetmann
1999 arXiv   pre-print
We show that the question whether a term is typable is decidable for type systems combining inclusion polymorphism with parametric polymorphism provided the type constructors are at most unary.  ...  The result of our paper can be used for the design of new type systems that combine both inclusion polymorphism and parametric polymorphism.  ...  In this paper, we investigate the problem of checking the well-typedness of terms in the presence of inclusion polymorphism combined with parametric polymorphism.  ...

On understanding types, data abstraction, and polymorphism

Luca Cardelli, Peter Wegner
1985 ACM Computing Surveys  
In this way we obtain a simple and precise characterization of a powerful type system that includes abstract data types, parametric polymorphism, and multiple inheritance in a single consistent framework  ...  data abstraction and since type inheritance is an important form of polymorphism.  ...  Also to Doug McIlroy and Malcolm Atkinson for very thorough reading of the manuscript, and to Rishiyur Nikhil and Albert Meyer for many useful comments.  ...

Interpreting Polymorphic FPC into Domain Theoretic Models of Parametric Polymorphism [chapter]

Rasmus Ejlers Møgelberg
2006 Lecture Notes in Computer Science  
This is the first model of a language with parametric polymorphism, recursive terms and recursive types in a non-linear setting.  ...  We show how this model gives rise to a parametric and computationally adequate model of PolyFPC, an extension of FPC with impredicative polymorphism.  ...  The model is to the authors knowledge the first model of the combination of parametric polymorphism, recursive terms and recursive types in a nonlinear setting.  ...

An ad hoc approach to the implementation of polymorphism

R. Morrison, A. Dearle, R. C. H. Connor, A. L. Brown
1991 ACM Transactions on Programming Languages and Systems  
There are a number of different categories of polymorphic expression: ad hoc, universal -parametric and inclusion; all of which have many advantages in terms of code reuse and software economics.  ...  Furthermore, the method ensures that any extra cost of implementation applies to polymorphic forms only and allows such polymorphic forms to persist over program invocations.  ...  Quintin Cutts and Graham Kirby are also thanked for their proof reading and suggestions.  ...

A Theory of Class [chapter]

Anthony J. H. Simons
1997 OOIS'96  
The theory is general, in that it encompasses many different approaches to type abstraction, such as type constructors, generic parameters, classes, inheritance and polymorphism.  ...  The theory has timely implications for emerging OMG standards and future language designs.  ...  Cardelli and Wegner (Cardelli and Wegner, 1985) considered that inclusion and parametric polymorphism were distinct forms of universal polymorphism, further distinguished from ad-hoc varieties such as  ...

Automated detection of informative combined effects in genetic association studies of complex traits

Nadia Tahri-Daizadeh, David-Alexandre Tregouet, Viviane Nicaud, Nicolas Manuel, François Cambien, Laurence Tiret
2003 Genome Research  
Here, we propose an automated method for the detection of informative combined effects (DICE) among several polymorphisms (and nongenetic covariates) within the framework of association studies.  ...  There is a growing body of evidence suggesting that the relationships between gene variability and common disease are more complex than initially thought and require the exploration of the whole polymorphism  ...  The algorithm identifies a subset of polymorphisms that are, either individually or in combination, associated with the phenotype.  ...

Datatype-Generic Programming [chapter]

Jeremy Gibbons
2007 Lecture Notes in Computer Science  
The term means different things to different people: parametric polymorphism, data abstraction, meta-programming, and so on.  ...  In these lecture notes, we expand on the definition of datatype-generic programming, and present some examples of datatypegeneric programs.  ...  We discuss the relationship between inclusion polymorphism and parametric polymorphism, and between these two and so-called ad-hoc forms of polymorphism, in Section 2.8 below.  ...
