Property container type objects

摘要

A framework being used for developing software system e.g. for a business application. This framework includes a number of object oriented classes which may be processed by a computer system. The invention provides an interface and a base class which implements this interface that allows specific data to be added to the objects of classes supporting the interface at runtime without the need for subclassing of the original class. Specific data added in this way to an object are referred to as properties of the object, and the interface introduced by this invention is referred to as the property container interface.
