Abstract

A method for obtaining a value via a rule engine implemented by a collection object associated with an object-oriented application. A request for the value includes a key, is received from the application, and is directed to a method of the collection object. The collection object is capable of storing the key and associated data, and providing the data in response to receiving the request. An overriding of the method of the collection object replaces the provision of the data by the collection object with a processing of the request by a rule engine external to the application. The rule is identified in a rule definition file external to the application based on an association between the rule and the key. An algorithm associated with the rule and included in the rule definition file is executed to provide the requested value.

Dependent claims

A method of operating a computer processing unit by obtaining a value via a rule engine implemented by a JAVA MAP in an object-oriented application, said method comprising:

receiving a request for a value from an object-oriented application operating on a computer processing unit, said request including a key and being directed to a Java Get object associated with said object-oriented application, wherein said JAVA MAP is capable of storing said key, storing data associated with said key, and providing said data in response to said receiving said request;
responsive to said receiving, processing said request by a rule engine external to said object-oriented application, said processing replacing said providing said data by said JAVA MAP via said Java Get object being overridden to invoke said rule engine;
identifying, via said processing said request, a rule included in a rule definition file external to said application, said identifying based on said rule being associated with said key included in said request, said rule definition file including an algorithm associated with said rule;
and
executing said algorithm on a computer processing unit via said processing said request, said executing resulting in the output of said value from storage in a computer processing unit.

A method for deploying a computing infrastructure, comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of performing a process of obtaining a value via a rule engine implemented by a JAVA MAP in an object-oriented application in a computer processing unit, the process comprising:

receiving a request for a value from an object-oriented application, said request including a key and being directed to a Java Get object associated with said object-oriented application, wherein said JAVA MAP is capable of storing said key, storing data associated with said key, and providing said data in response to said receiving said request;
responsive to said receiving, processing said request by a rule engine external to said object-oriented application, said processing replacing said providing said data by said JAVA MAP via said Java Get object being overridden to invoke said rule engine;
identifying, via said processing said request, a rule included in a rule definition file external to said application, said identifying based on said rule being associated with said key included in said request, said rule definition file including an algorithm associated with said rule;
and
executing said algorithm via said processing said request, said executing resulting in the output of said value from the storage of a computer processing unit.
