  • Apparatus and method for automatically propagating a change made to at least one of a plurality of objects to at least one data structure containing data relating to the plurality of objects
    Patent number: 6192368
    Abstract: According to the present invention, an object change manager includes methods afterCreation( ), beforeDeletion( ), beforeChange( ) and afterChange( ) that may be invoked when an object is changed. The object change manager automatically updates all data structures, such as indexes and has tables, that correspond to the object being changed when one of these methods is called. The object change manager is an extensible framework that allows a programmer to define custom change management environments. The object change manager of the preferred embodiments is a portion of code that automatically propagates changes to objects to their corresponding data structures in a way that is transparent to the programmer, without requiring excessive overhead in the object infrastructure code.
