Creating a Server-Side Component
Typical server-side Vaadin applications use server-side components that are rendered on the client-side using their counterpart widgets. A server-side component must manage state synchronization between the widget on the client-side, in addition to any server-side logic.
Basic Server-Side Component
The component state is usually managed by a shared state, described later in "Shared State".
public class MyComponent extends AbstractComponent {
public MyComponent() {
getState().setText("This is MyComponent");
}
@Override
protected MyComponentState getState() {
return (MyComponentState) super.getState();
}
}
