Method and apparatus for implementing type-safe heterogeneous property lists

Abstract

A method and apparatus for implementing type-safe, heterogeneous object-oriented property lists. A library of classes and template classes implementing a heterogeneous property list is defined, wherein each object of the property list includes a property name and an associated property value of a selected property type. Instantiation of objects having equal property names and unequal property types is prevented with a constructor, and template functions are provided each of which accesses the objects of the property list according to a type of data passed to the function.
