JScript .NET allows developers to use untyped variables, and can sometimes infer their type from their usage to optimize the compiled code. On the other hand, Java requires all variables to be typed. JScript .NET can add properties and methods to objects in run-time, while Java objects always conform to their declared interface.
C# makes use of reification to provide "first-class" generic objects that can be used like any other class, with code generation performed at class-load time. [29] Furthermore, C# has added several major features to accommodate functional-style programming, culminating in the LINQ extensions released with C# 3.0 and its supporting framework of ...
That is, it returns the true, original type of the object, irrespective of any type casting. In these languages, the typeof operator is the method for obtaining run-time type information . In other languages, such as C# [ 2 ] or D [ 3 ] and, to some degree, in C (as part of nonstandard extensions and proposed standard revisions ), [ 4 ] [ 5 ...
Metaprogramming is a computer programming technique in which computer programs have the ability to treat other programs as their data.It means that a program can be designed to read, generate, analyse, or transform other programs, and even modify itself, while running.
In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation. External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable.
The LINQ to Objects provider is used for in-memory collections, using the local query execution engine of LINQ. The code generated by this provider refers to the implementation of the standard query operators as defined on the Sequence pattern and allows IEnumerable<T> collections to be queried locally. Current implementation of LINQ to Objects ...
The object collaboration diagram shows the run-time interactions: In this example, the Client object sends a request to the top-level Composite object (of type Component) in the tree structure. The request is forwarded to (performed on) all child Component objects (Leaf and Composite objects) downwards the tree structure.
In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state and behavior that are each either associated with a particular object or with all objects of that class.
