Abstract
A method of coupling rules to a data domain of an object-oriented computer program. During run time, the coupling permits the computer to use rules to directly access user-defined objects for both the matching and the action phases of the inferencing process. Inferencing is implemented with an inference class object and user-defined class object are derived from a working memory element class.
Claims9
A computer implemented method of creating a system of rules for use on a computer having an object-oriented data domain comprising the steps of:
- compiling at least one rule having a premise and an action, wherein the premise references a user-defined class upon which the rule will inference;
- compiling a definition for said user-defined class, such that said user-defined class inherits from a working memory element class;
- and
- binding an inference class object to a rule, adding user-defined class instances to a working memory element class, and calling an inferencing process after a rule calling sequence has been inserted in the object-oriented domain, such that said rule calling sequence defines an inference class.
