APPLICATION PROGRAM DEVELOPING METHOD AND COMPUTER SYSTEM FOR PLATFORM AT TIME OF DISTRIBUTED ADAPTIVE EXECUTION

摘要

PROBLEM TO BE SOLVED: To develop a program without describing the details of distribution and application by achieving the application in the case of distributed adaptive execution while using a metha-object programming model. SOLUTION: An adaptive object 20 is executed by one adaptive software method 21 and two non-adaptive software methods 22 and 23. Access to three implementations 21a-21c included in the adaptive software method 21 is controlled by a software selector 24 including a reference to one of them and a switching software wrapper 25. When the adaptive software method 21 is called, which implementation is to be executed is inquired to the software selector 24 by the switching software wrapper 25 and according to the reference stored in the software selector 24, selected one of implementations 21a-21c is executed.
