Hi Deva,

IF_COMPONENTCONTROLLER is an interface. When we need to refer to component controller, we need to create a variable which should be of IF_COMPONENTCONTROLLER type.

IG_COMPONENTCONTROLLER is also an interface. When we access all publicly accessible methods, variables declared in the component controller , we have attribute WD_COMP_CONTROLLER ( contained in view controller ) which is a reference variable of the type IG_COMPONENTCONTROLLER.

I hope it helps.

Hi Deva,

1. IG_COMPONENTCONTROLLER

if you want to use used component in your view you have to declare the usage of that component. your view controller already contains the attribute WD_COMP_CONTROLLER, which is a

reference variable of the type IG_COMPONENTCONTROLLER. In each view controller, you

can use the attribute WD_COMP_CONTROLLER to access all publicly accessible methods of

the component-global generated interface of the corresponding component controller.

2. IF_COMPONENTCONTROLLER

each component has a local interface, the controller attribute WD_THIS is a reference to this local interface.Depending on the controller, a reference variable can be of IF_COMPONENTCONTROLLER type. now this type of refrence variable will allow you to use methods and attribute of local component controller.
