AddHandler _builder._dispatcher.OnProcessRequest, AddressOf _builder._coordinator.Run AddHandler _builder._dispatcher.OnRequestCompleted, AddressOf theFormMain.RequestCompletedHandler AddHandler _builder._dispatcher.OnStop, AddressOf _builder._coordinator.Stop End Sub End Class By wiring all the complex objects together with event notifications, the important classes remain completely decoupled from all others. Thus, you can implement and fully test the Coordinator and the two Worker classes independently. A side effect of the introduction of events to replace all interclass calls is a fragmentation of the system. Looking at the implementation of the Coordinator, for example, one can t understand how the class functions with other parts of the system, because the code shows events being fired, with no evidence of where the resulting notifications go. The event handlers are not determined until run time. But this is exactly the situation you wanted to create in the first place: You wanted each class to be fully decoupled from all others. The only way to achieve this is by wiring objects together at run time, so the only way to determine how all the classes work together is by looking at a system s wiring diagram. In the hardware world, things are similar. Integrated circuits are conceptually equivalent to objects. Each IC is completely detached from all other ICs, before being added to the system. By looking solely at a circuit diagram of the internal design of an IC, you can t tell how the IC functions in relationship to other parts of the system. ICs come with pins, because they are designed to be wired to other components, so the only way to determine how everything works together is by looking at the wiring diagram of the system.

The binders described so far have all had one thing in common: The connections they wired were all described statically. The source code specifies exactly which inputs and outputs to wire together. There is another type of Binder that can wire inputs to outputs dynamically, in the sense that the list of inputs and outputs to wire is determined at run time. The source code no longer contains a static list of connections to be established. Dynamic binding can be nondeterministic, because before running a system you might not be able to predict which connections will be made. It is the system, and not the programmer, that ultimately decides what bindings are made in the system. Dynamic binders are driven by notifications from the system, and from a certain perspective behave like a living organism. When specific stimuli are sensed, the system reacts by creating new objects and connections. Systems that are capable of growing and adapting to input from the environment are known as evolvable systems, and dynamic binding is a fundamental part of any such system. Describing a dynamic system is challenging, because the system changes over time. A common approach is to diagram snapshots of the system at important times in its lifetime, much the way you might draw a picture of a person. If a system s evolution pattern is predictable, then you know what objects and connections might appear at some point. The wiring diagram in Figure 10-50 shows a simple evolvable system whose growth is predictable.
