OBJECT LINKAGE DEVICE USING MESSAGE TYPES

摘要

In object linkage through messages, various message types are handled, and synchronous processing between objects is carried out simply and flexibly. In advance message types are hierarchically sorted. A message-action relation storage section (102) holds a message-action relation table (103) that is organized by message type. A message received is matched in the message-type sorting/matching section (107). If it is any type that is handled by the message-action relation storage section (102), it is passed; if not, it is discarded. According to the passed message, an action taking section (104) takes an action. In the synchronous processing, a subject name rewriting object is prepared, and the subject name of the received message is rewritten to a master subject name and transmitted. An object to be synchronized has descriptions of an action that synchronizes with the message contents of the master subject name.
