Abstract
Abstract An object-oriented mechanism is disclosed that allows new configuration data to replace existing configuration data within an existing object-oriented program. The new configuration data allows an OO program to be quickly and easily generated from an existing OO program without manually changing the source code of the existing OO program. When a factory object creates an object in the existing OO program, the new configuration data that defines a modified class is used to create the object. In this manner class substitution or redefinition in an OO program is easily accomplished, thereby allowing a new OO program to be easily generated from an existing OO program (or framework).

Claim 7
Independent Claim
116 words
An apparatus comprising: a processor; a memory coupled to the processor; an existing object-oriented program residing in the memory; at least one existing configuration data object residing in the memory that determines the attributes of at least one existing class within the existing object-oriented program; and an object-oriented interface mechanism residing in the memory that replaces at least one existing configuration data object that specifies a first of the at least one existing classes with new configuration data that specifies a replacement class, wherein said new configuration data comprises persistent container elements to determine a location and class of objects instantiated under said replacement class, wherein said persistent container elements include security, persistence, transactions and concurrency.
Claim 8
Independent Claim
116 words
An apparatus comprising: a processor; a memory coupled to the processor; an existing object-oriented program residing in the memory; at least one existing configuration data object residing in the memory that determines the attributes of at least one existing class within the existing object-oriented program; and an object-oriented interface mechanism residing in the memory that replaces at least one existing configuration data object that specifies a first of the at least one existing classes with new configuration data that specifies a replacement class, wherein said new configuration data comprises persistent container elements to determine a location and class of objects instantiated under said replacement class, wherein said persistent container elements include security, persistence, transactions and concurrency.
