import com.sap.test.wdp.IPrivate<View_name>;

Hi,

1.WDcontext wdcontext give us the access to the whole context ...we can access any node attribute under the context using wdcontext..it gives full control of context...

for example like...

wdcontext.node

wdcontext.currentattribute..

wdcontext.currentelement...

2.Import we are importing here interface view which gives the detail about the view...

A view will have such an import like IPrivate<view name> , where a view is is made up of different user interface elements, which can be nested in each other. Additional to the layout, a view also contains a controller and a context. The data to which the elements of the view can be bound are stored and managed in the view context, enabling them to be represented or used on the screen. The view controller can contain methods for data retrieval or for processing user input ( like setters and getters for such context attributes )

Hope this info is some what relevant to your question

Hi,

import com.sap.test.wdp.IPrivate<View_name>;

This indicates the import of an interface of the view. It is created by the WD frame work when you create a view. It consists the details about context and methods of the view.

wdContext is refrence to your context of the view. Using this we can refer anu node/attribute in the context.

Hope you understand it.

BUT What do you mean by interface of the view?

what are its charecterstics?

[Former Member]

Interface in general is used to expose the methods and the Context variables of a Controller.....Interface for a view is used when a view from another component needs to call the view in the other component....

Hope it helps.
