ABSTRACT:
Method and arrangement for dispatching messages between instance specific dispatch tables of objects, when a particular object does not have resident the method called for execution in response to a message directed toward it. When a message is sent to a first object and the method called for execution is not resident or associated with the first object, the first object may expressly reference another object of the same class which may contain the required method. The message is according dispatched to another instance specific dispatch table associated with an object which may be able to execute the method called for by the message initially transmitted. Upward chaining between instance, class, and superclass level dispatch tables, and method supercalls canceling the effect of method overriding by instance level methods are included in the method and arrangement.
