connection Interface Controller and Component Controller

[Former Member]

Hi experts,

I need your help,

some of you know the meaning the following icons:

<a href="http://ppalli.homeip.net/SAP_Netweaver/context1.JPG">context interface controller</a>

<a href="http://ppalli.homeip.net/SAP_Netweaver/context2.JPG">connect context interface controller to component controller</a>

I'm editing a standard DC and I find these icons when a component's interface controller connects a component controller of another component

<a href="http://ppalli.homeip.net/SAP_Netweaver/interface_component.JPG">interface_component</a>

I hope can help me, thanks

...sorry for my English

Hi Pedro,

Each component has a attached interface controller. Its kind of class-interface relation in java (Not very strict in 04s but very strict in CE (7.0 onwards) )

In short if you want to expose any functionality (event,methods,plugs,interface views etc) out of componet you do it via defining the functionality in the corresspoing interface controller. It same what you seeing via

<a href="http://ppalli.homeip.net/SAP_Netweaver/interface_component.JPG">interface_component</a>.

now each controller e.g. interface component controller holds data. That data is stored in the context of the controller. THis is what you see via <a href="http://ppalli.homeip.net/SAP_Netweaver/context1.JPG">context interface controller</a>.

As data is held in interface component, the component controller also holds data in its context. To map the data you have to binding of context nodes and attributes between component controller context and interface component controller. THis is waht you refer via <a href="http://ppalli.homeip.net/SAP_Netweaver/context2.JPG">connect context interface controller to component controller</a>
