The net.openwings.component.Component interface is the centerpiece
of the service-based component architecture provided by Openwings.
It abstracts away the details of using synchronous (method-based)
and asynchronous (messaging or event-based) communication between
components.
The Component interface is just one of two layers of interfaces
for providing and using services in the Openwings Component Services
API. The other layer is net.openwings.component.ComponentComplex.
Each is intended to provide a different level of functionality,
as we'll see later.
A static class called net.openwings.component.ComponentFactory
contains methods for obtaining instances of classes implementing
each of these interfaces.
Finally, UseServiceListener is another important piece of the
component API. UseServiceListener is used by a component to register
ongoing interest in a service. For example, listeners could be
used to notify components of a significant change in a screen
display.
