Method and apparatus for optimizing interface dispatching in an object-oriented programming environment

摘要

A method and apparatus perform optimizations for interface dispatching in an object-oriented programming environment. Specifically, section of code that dispatches an interface method on a particular object is determined. A table of interfaces associated with the class is examined to locate the interface specified by the dispatch. An offset for a location of the interface is determined, and the offset is cached in a class cache. The class cache is then examined when a next dispatch is received to determine whether the interface associated with the offset in the class cache matches the interface specified by the next dispatch.
