MECHANISM FOR DYNAMICALLY ASSOCIATING SERVICE SUBORDINATE REPRESENTATIVE WITH OBJECT AT THE TIME OF EXECUTION

摘要

PROBLEM TO BE SOLVED: To provide a mechanism for dynamically associating subcontracts with respective servants at the time of execution instead of association with a servant class or an interface at the time of compiling. ;SOLUTION: A dynamic associative data structure 200 is provided with a server representation class 206 showing the single sub-contract, a servant base class 204 associated with a servant object 220 generated at the time of execution and a link mechanism for forming a link 222 between the server representation class 206 and the servant object 220. The server representation class 206 provides functionality to the single subcontract. At the time of execution, the servant object 220 is exteriorized from the servant base class 204 or much more derived class. The servant object 220 uses functionality provided by the sub-contract through the link mechanism.;COPYRIGHT: (C)1998,JPO
