com.vaadin.ui.CustomComponent
Custom component provides simple implementation of Component interface for creation of new UI components by composition of existing components.
The component is used by inheriting the CustomComponent class and setting composite root inside the Custom component. The composite root itself can contain more components, but their interfaces are hidden from the users.
