COSBasedObject
abstract public class COSBasedObject implements IAttributeSupport,ICOSObjectListener(Code)
The abstract superclass for all objects/data structures that are build on the basic COSObject types.
The base COSObject will represent the state while this wrapper will provide the behavior.
The COSBasedObject and its base COSObject are always closely related, all changes are immediately reflected in both objects.
The COSBasedObject uses a META framework that ensures identity (you will always get the identical COSBasedObject for a COSObject created via META) and defines the lifecycle of the COSBasedObject . A COSBasedObject should always be created using META.createNew or META.createFromCos.

A COSBasedObject based on a COSDictionary can use some convenience methods for generic access to its fields. As a convention, filed names are always declared with the associated COSBasedObject as public static final COSName DK_.
The COSBasedObject implements IAttributeSupport . Client code can use this feature to transparently associate objects with objects from client code, for example for caching or client defined relationships.
