Each object has a position value, which
indicates where it will be displayed.
The position is defined by the
IlpPosition interface which has the following
predefined implementations:
IlpPoint for shelves placed in the
component
The position value can originate from the
back end as an attribute of the corresponding business object, or
from separate data storage through the equipment component API, or
from explicit end-user interactions to move objects in the
component.
