public class MapChoice extends AbstractChoice
A choice between different possible mapping functions of a set of values to a set of placeholder ids. A resolution of this choice consists of choosing a unique value for each placeholder id (hence a map choice is valid iff there are at least as many values as placeholder ids).Each unique set of mappings (pairs) from values to placeholder ids is a separate possible alternative of this choice. The alternatives are not listed explicitly but are generated as needed.
