Classifying Java class transformations for pervasive virtualized access

Phil McGachey, Antony L. Hosking, J. Eliot B. Moss
2009 Proceedings of the eighth international conference on Generative programming and component engineering - GPCE '09  
We consider the constraints imposed upon pervasive class transformation within Java, and present a framework for systematically rewriting arbitrary applications.  ...  Our system accommodates all system classes, allowing both user and system classes alike to be referenced using a single object model.  ...  Figure 3 shows the transformation of a single user class X to conform to the RuggedJ object model.  ...

Schema transformation without database reorganization

Markus Tresch, Marc H. Scholl
1993 SIGMOD record  
We s h o w that data independence, which is a neglected concept in object databases, helps to avoid reorganizations in case of capacity preserving and reducing schema transformations.  ...  We informally present a couple of examples to illustrate the idea of a schema transformation methodology that avoids database reorganization.  ...  This process is called (proxy) object unication. We use extend views to de ne same-functions that identify objects from one class that are \the same" as an object from another class.  ...

Maintaining behavioral consistency during schema evolution [chapter]

Paul L. Bergstein, Walter L. Hürsch
1993 Lecture Notes in Computer Science  
We examine the problem of how to ensure behavioral consistency of an object-oriented system after its schema has been updated.  ...  The latter kind is a special case of the former in that any object-preserving transformation can be regarded as an object-extending transformation.  ...  One kind consists of the object-extending class transformations, presented formally in LHX93]. The other kind consists of the object-preserving transformations, presented formally in Ber91].  ...

Fast portable orthogonally persistent JavaTM

2000 Software, Practice & Experience  
Two type parameterization [1, 6] apply byte-code transformation at class loading time, these transformations are applied by using a specialized class loader.  ...  This framework consists of a number of simple but powerful transformations that, among other things, allow us to semantically extend Java to provide orthogonal persistence.  ...  The 'Class Replacement' transformation is extended with a replacement of a class for an abstract API equivalent class.  ...

A language for knowledge description, whose syntactical objects are entities, relationships, transformations, and constraints, and which allows four levels of specificity and abstraction is proposed.  ...  Four levels of specificity and abstracinference mechanism that interprets the user's input tion are then identified: instances, classes, about instance-level objects in his application, subschemas, and  ...  An instance (of a class) is an object that can be attributes, as well as other transformations.  ...

Open GADTs and declaration-site variance

Paolo G. Giarrusso
2013 Proceedings of the 4th Workshop on Scala - SCALA '13
