Abstract: A method for invoking an arbitrary sorting technique in a type-safe way. In one aspect, the method comprises the steps of providing a hierarchical schedule class comprising a schedule float subclass and a sorting schedule float subclass, subsumed by the schedule float subclass. The sorting schedule float subclass, in turn, comprises a schedule attribute class; a filter class; and a pair compare class. The method further includes using the hierarchical schedule class with each of an independent group consisting of a schedule attribute strategy, a filter strategy and a pair compare class strategy.
