Description
The Adapting Objects service allows a consumer to access shared data in a relevant way within the current context. Classes can retrieve information about various objects by adapting them to the applicable model. For example, a Javadoc view can access information necessary to render javadoc of the selected class, while an Overview view can access the structure of the class necessary to render a tree.
Consumer
In order for a class to be able to adapt an object, there needs to be a respective ModelEditor. The ModelEditor implements two interfaces which are essential for the Adapting Objects service: IAdaptable and IModelProvider. Once the ModelEditor is implemented, a client class can access the adapted object without casting.
Usage

it would be nice to link to some actual api docs, but alas they don't live anywhere yet
