March The Amusing Ourselves to Death comic: I proactively contacted them, and received notification that they would prefer the comic was removed. Respecting their wishes, I removed the comic without hesitation.
Historical background[ edit ] The earliest computers were programmed in their native assembly languagewhich were inherently reflective, Reflective account on communication these original architectures could be programmed by defining instructions as data and using self-modifying code.
As programming moved to compiled higher-level languages such as AlgolCoboland Fortran but also Pascal and C and many other languagesthis reflective ability largely disappeared until programming languages with reflection built into their type systems appeared. Uses[ edit ] Reflection helps programmers make generic software libraries to display data, process different formats of data, perform serialization or deserialization of data for communication, or do bundling and unbundling of data for containers or bursts of communication.
Effective use of reflection almost always requires a plan: A design framework, encoding description, object library, a map of a database or entity relations. Reflection makes a language more suited to network-oriented code.
For example, it assists languages such as Java to operate well in networks by enabling libraries for serialization, bundling and varying data formats. Languages without reflection e. C have to use auxiliary compilers, e. Reflection can be used for observing and modifying program execution at runtime.
A reflection-oriented program component can monitor the execution of an enclosure of code and can modify itself according to a desired goal related to that enclosure. This is typically accomplished by dynamically assigning program code at runtime.
In object-oriented programming languages such as Javareflection allows inspection of classes, interfaces, fields and methods at runtime without knowing the names of the interfaces, fields, methods at compile time.
It also allows instantiation of new objects and invocation of methods.
Reflection is also a key strategy for metaprogramming. In some object-oriented programming languages, such as C and Javareflection can be used to override member accessibility rules. For example, reflection makes it possible to change the value of a field marked "private" in a third-party library's class.

Some of these features are the abilities to: Discover and modify source-code constructions such as code blocks, classesmethods, protocols, etc. Convert a string matching the symbolic name of a class or function into a reference to or invocation of that class or function.
Evaluate a string as if it were a source-code statement at runtime. Create a new interpreter for the language's bytecode to give a new meaning or purpose for a programming construct. These features can be implemented in different ways. In MOOreflection forms a natural part of everyday programming idiom.
When verbs methods are called, various variables such as verb the name of the verb being called and this the object on which the verb is called are populated to give the context of the call. Security is typically managed by accessing the caller stack programmatically: Since callers is a list of the methods by which the current verb was eventually called, performing tests on callers  the command invoked by the original user allows the verb to protect itself against unauthorised use.Graphic Products - Providing safety & visual communication solutions since Home of DuraLabel - the global leader in industrial label & sign printers.
