```
public interface Pageable
```
Represents a component that can be displayed in multiple pages but cannot be controlled by an external paging controller.
- Paginated: a multi-page component whose pagination is controlled by an external page controller (Paginal).
- Paginal: the paging controller used to control the pagination of Paginated.
- Pageable: a multi-page component that handles pagination by itself.
Note: a component that can be displayed in multiple pages can be implemented in two ways.
1) If it can be controlled by an external paging controller (i.e., Paginal), it shall hold an reference to one of the paging controllers. And, it doesn't need to implement Pageable. Example: grid, listbox and tree.
2) If it cannot be controlled by external controller, it shall implement the Pageable interface.
