Abstract

For interactive map definition (IMD) a full list process is required to dispatch the appropriate process to perform the requested function. For example, if an "E' is entered for a font, the font editor should be invoked; if it is entered for a map, the map editor should be invoked, etc. In addition, IMD full list needs to be "open ended' and support entities on the map specification library (data base). It has no prior knowledge of other entities.

Generalized Interactive Map Definition Full List Dispatcher

For interactive map definition (IMD) a full list process is required to dispatch the appropriate process to perform the requested function. For example, if an "E' is entered for a font, the font editor should be invoked; if it is entered for a map, the map editor should be invoked, etc. In addition, IMD full list needs to be "open ended' and support entities on the map specification library (data base). It has no prior knowledge of other entities.

IMD despatches its processes (and those of other products) using process vector tables (PVTs) which define the hierarchical structure and the process names that are used to support the dialogue with the end user. This table has been extended so that each process can have a "process function code' (edit, generate, copy, delete, test, etc.) and a list of the data base entities that are supported by the process (map, mapgroup, font, table, etc.). Thus the full list process can scan the PVT to find the appropriate process to dispatch by getting a match with the process function code and the data base entity type. More processes can be added without affecting the full list process.

The drawing is a flowchart of the processor search sequence.
