What is the relationship between component family, component type and renderer type?

Component Type

While not a property of UIComponent, the component-type is an important piece of data related to each UIComponent subclass that allows the Application instance to create new instances of UIComponent subclasses with that type.

Component Family

Each standard user interface component class has a standard value for the component family, which is used to look up renderers associated with this component. Subclasses of a generic UI Component class will generally inherit this property from its superclass, so that renderers who only expect the superclass will still be able to process specialized subclasses.
