Component Mechanisms

We should consider the inherent requirements for all components.

• All of the components, public functions, and data should be accessible via a simple interface.

• We should be able to add/delete/modify our component's actions simply.

Message sending is the means of controlling your component. The calling component will send a message to the called component telling it what to do.

There are various methods you could employ to send messages ...
