}

}

The general API is define in the section Graphic.

API specific to the adapter is defined below.

@@method(public, instance) (id)value;
  Call like this:

myValue = [myAdapter value];

Returns the native view object. Once you have a handle to that view object you may call upon it as needed. Probably the best thing to do is to make remedial changes to it in the script and then register the adapter with the controller to set it up further.
