JavaScript extensions – An enhanced type system is introduced to emulate object-oriented constructs such as namespaces, classes and interfaces; and to perform reflection on client types. Abstraction API – Common operations on the DOM (retrieving elements, setting styles and other manipulations) are automatically translated by the library ...
Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects. Reflection is also a key strategy for metaprogramming. In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules. For C#-properties this can be achieved by ...
The java.lang.Class [2] class is the basis of more advanced introspection. For instance, if it is desirable to determine the actual class of an object (rather than whether it is a member of a particular class), Object.getClass() and Class.getName() can be used:
C# uses 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 ...
.NET Reflector is a class browser, decompiler and static analyzer for software created with .NET Framework, originally written by Lutz Roeder. MSDN Magazine named it as one of the Ten Must-Have utilities for developers, [1] and Scott Hanselman listed it as part of his "Big Ten Life and Work-Changing Utilities".
A schema for a particular use of protocol buffers associates data types with field names, using integers to identify each field. (The protocol buffer data contains only the numbers, not the field names, providing some bandwidth/storage savings compared with systems that include the field names in the data.)
The state of the algorithm is maintained locally by the concrete visitor class. The element declares an accept method to accept a visitor, taking the visitor as an argument. Concrete elements, derived from the element class, implement the accept method. In its simplest form, this is no more than a call to the visitor's visit method.
To the left is a list of the object itself (with the label "self"), followed by the instance variables in the object, which will include numbered instance variables in sequences such as strings and arrays. To the right is a workspace pane. Selecting a name in the list replaces the workspace's contents with a print string of the selected variable.
