NSObjectController is a Cocoa bindings-compatible controller class. Properties of the content object of instances of this class can be bound to user interface elements to access and modify their values.

By default, the content of an NSObjectController instance is an NSMutableDictionary object. This allows a single NSObjectController instance to be used to manage many different properties referenced by key-value paths. The default content object class can be changed by calling setObjectClass:, which subclasses must override. Your application should use a custom data class that is key-value compliant whenever possible.
