Diff between Component Interface and Interface controller

[Former Member]

Hi,

Can anyone explain me what is the difference between component interface defined under web dynpro component interfaces and component interface under a component?

Thanks,

Hi Imtiyaz

- Standalone Component Interface is just interface without any concrete implementation. Like Java interface.

- Component Interface under a Component is an interface part of the component. It allows the component to communicate with other components.

- Component can implement one or more Standalone Component Interfaces. In the case Component Interface will be extended with public methods/interface windows derived from the Standalone Component Interfaces. This is like Java class implements Java interface.

Hi Sergei,

Can you provide me some good examples for Standalone Component Interface and for Component Interface under Component.

Hi,

A component is a reusable UI program package.

A component can copmmnicate with other one via component interface.

Web Dynpro Component Interface is just like an Interface.

Let's say you have two components and you want to show them in third component. one way is you create two used Components, because you know at design time which component you want to show..

If you don't know at design time which component to be shown, you just create a webdynpro component interface and you implement this interface in both the components, and in your main component you just create a used component of this interface component, and handle dynamically which instance of the component you want to show..

Hi,

Component Interface is the entity which is used when you want to use the functionality defined in some other component i.e. if your main component is acting as a parent comopnent then the child component usage should be defined via this interface controller under Component Interface, so that main compo will access it via childs Interface Controller.

Other node under this , Interface view , gets generated for every creation of window , Interface view is entry point into our application for web Dynpro framework

check out these ex for the Component Interface and node under this,
