	Dirk Riehle: Dissertation, Chapter 4: Framework Design
		A callback role type is a free role type of a framework that has a non-empty set of operations.
		Callback role types are important, because having to define operations has the most visible impact on the implementation of a framework's class model in a particular programming language.
		Callback role types are the role modeling equivalent of callback interfaces as defined in the previous subsection on traditional coupling mechanisms.

	Callback (computer science) - Wikipedia, the free encyclopedia
		A callback can be used as a simpler alternative to polymorphism and generic programming, in that the exact behavior of a function can be dynamically determined by passing different (yet compatible) function pointers or handles to the lower-level function.
		A callback may also be regarded as a form of runtime binding, as discussed in the influential Design Patterns book (see the Chapter 1 summary).
		Callback functions are also frequently used as a means to handle exceptions arising within the low level function, as a way to enable side-effects in response to some condition, or as a way to gather operational statistics in the course of a larger computation.

	The Callback Interface
		If a callback is registered with an event, the callback is called when the event occurs.
		Callbacks can be filtered, so that they are only called in specific situations.
		The callback is delivered before it is actually deleted in order to enable processing of the entity.

	Enrollment for Computer Science Majors Declines
		A new report has found that 10 percent fewer students enrolled in computer science and engineering programs in the 2003-2004 academic year compared with the previous school year, USA Today reports.
		The Computing Research Association, a group for professors of computer science, computer engineering, and related fields, conducted the study.
		While the job market for computer majors remains tight, some companies are concerned that if enrollment continues to fall, they will be unable to find qualified workers in the future.

		The trace data relevant to a callback function's associated TAU event type are delivered to the function via its arguments.
		The callback table should be initialized by associating each of its elements with a complementary callback function.
		Each element of the callback table must be initialized to a viable function or 0.

		In computer science, a callback is a concept, which allows a low level layer to call a function from a higher level layer, when usually, the higher level calls the low level layer.
		It is used in Windows to set an exception handler.

		POET's event-handling mechanism is based on callbacks that occur when a client method is called after the POET system encounters a specific insert, lock, or update event.
		When working with callbacks, keep in mind that the class that contains the callback method must be derived from the base class PtCallback, and that the callback method must bind to the event.
		The mechanism to define this callback is identical to that of the insert event.

	Dr. Dobb's \| IOStreams Storage \| December 9, 2005
		Maciej Sobczak is a Ph.D. student at the Institute of Computer Science, Warsaw University of Technology.
		The idea behind callback functions is that you can ask the stream object to call the specified function (usually, your function) when something important happens.
		After writing a couple of your own classes that use the additional storage in stream objects, you quickly discover that the way you use this functionality is repeatable to the extent that a special, reusable wrapper would be quite desirable.

		In its most general sense, computer science (CS or compsci) is the study of computation and information processing, both in hardware and in software.
		In practice, computer science includes a variety of topics relating to computers, which range from the abstract analysis of algorithms, formal grammars, etc. to more concrete subjects like programming languages, software, and computer hardware.
		As a scientific discipline, it is distinct from mathematics, programming, software engineering, informatics, and computer engineering, although there are significant overlaps and no clear demarcation.

	Callbacks
		In computer science lingo, the function passed as an argument is called a callback, since it is "called back" by the other function.
		He does some low-level bit-twiddling that is perfectly legal and portable, but the optimizer on the Kuck and Associates compiler causes wrong answers to be generated at run-time.
		So I wrote my own callback library that has mostly the same functionality and uses his ideas, but implements things a bit differently.

	FSMGenerator - Finite State Machine generating software.
		The callback name must refer some sort of “plugs” within the user’s software, which provide the interface between the created FSM and the user’s software.
		As it can be seen, the identification of the states, events, transitions, callbacks and hooks is name-based.
		Moreover, the purpose of Generator module is not only to provide FSM generators for required destination programming languages (C, CPP and Java), but also provide a framework for tool extension by adding generators for additional programming languages.

	FAQ - TSpaces - Computer Science Research at Almaden
		So a callback because of an event registration will share a socket that was already established instead of creating a new socket.
		You should be able to use the event callback with the specific template that you are interested in - this way, all clients will be able to see the new tuples.
		So, in short, I think the event callback is the best way to go when several clients may need the same tuple.
