Abstract
In an object-oriented run-time environment, inheritance and disinheritance of methods and data to and from an object is facilitated. When an object is invoked, a method within the object is called. Execution of this method may, however, not be possible because, e.g., a data type passed to the method may not be supported thereby. In response to this condition, the object invokes a process that inherits a required method and/or datum into the object. For example, a method that does support the previously unsupported data type may be inherited. After inheritance is completed, the object is reinvoked with the previously unsupported data type. Processing may then continue using the inherited method. After the inherited method is no longer needed, it may be disinherited from the object.
