and typed LR parsing. We show that existing object-oriented programming languages such as Java and C# can express GADT definitions, and a large class of GADT-manipulating programs, through the use of generics, subclassing, and virtual dispatch. However, some programs can be written only thr...

PHP Data TypesVariables can store data of different types, and different data types can do different things.PHP supports the following data types:String Integer Float (floating point numbers - also called double) Boolean Array Object NULL Resource...
In this example, we're creating an object-oriented C++ program that creates an abstract data type in the form of a stack, in which items can be pushed onto the top and popped off the top. The program simulates your browsing history. Each page you visit is stored in a stack. As you...
In this paper we present the type system of the TIGUKAT database programming language. It is a highly parametric object-oriented type system that combines multiple dispatch with reflexivity, separation of interface and implementation, precise behavior typing, and union and intersection types. We demon...
This paper is based on our experiences in designing, formalizing and implementing the deductive object-oriented database (DOOD) system ROCK & ROLL [5, 7, 13, 14, 15, 16]. Our overall goal has been to bring together the deductive and the object-oriented approaches in a clean, uniform and...
Programming in Visual FoxPro Visual FoxPro is a powerful interactive data management tool, but you also can access the full power of Visual FoxPro by creating applications. Understanding object-oriented programming techniques and the event-driven model can maximize your programming productivity....
