Data communication method, data communication system, and program

摘要

A method and system to enable communications between components using a single procedure so that a user is not required to consider compatibility among protocols when programming or maintaining programs. A data communication class which enables communications regardless of matching among protocols, a data communication interface, and an implementation class for each protocol are prepared so as to operate or develop an application program. The data communication class is initialized in the application program and a communication interface calls a communication method from its instances. The communication data is passed as an argument of the communication method. When a data communication instance is generated, the implementation class corresponding to a protocol specified for the property is set in the instance.
