func RegisterPriorityFunction2 ¶ added in v1.5.0
func RegisterPriorityFunction2( name string, mapFunction algorithm.PriorityMapFunction, reduceFunction algorithm.PriorityReduceFunction, weight int) string
RegisterPriorityFunction2 registers a priority function with the algorithm registry. Returns the name, with which the function was registered. FIXME: Rename to PriorityFunctionFactory.
