ATTRIBUTE IMPORT AND EXPORT BETWEEN NODES OF A DIRECTED GRAPH

摘要

ATTRIBUTE IMPORT AND EXPORT BETWEEN NODES OF A DIRECTED GRAPH A method for constructing and executing an application comprising a plurality of procedures, wherein the procedures are represented by function graphs, each function graph including a plurality of nodes, including an initialization node for handling initialization functions, a dialog node for handling processing functions, and an exit node for handling exit functions. The nodes may import and export variables, and the function graph includes an import table for specifying the import variables for each of the nodes and an export table for specifying the export variables for each of the nodes. The nodes are loosely coupled and need not be aware of the import/export variables for other nodes.
