This paper presents the DT Framework, a collection of object-oriented classes representing a generalized framework for inheritance managment and table-based method dispatch. It demonstrates how most existing table-based dispatch techniques can be generalized and made incremental so that relevant entries in the dispatch table are modified each time a selector or class heirarchy link is added or removed. The incremental nature makes the framework highly efficient with low millisecond average modification time, and supports table-based dispatch even in schema-evolving languages. During table maintenance, the framework detects and records inheritance conflicts, and maintains information useful during compile-time optimization.
