Interface IAssignments

All Superinterfaces:

IAssignmentsRead, IAssignmentsToMultipleRead

All Known Implementing Classes:

Assignments

public interface IAssignments
extends IAssignmentsRead

A set of assignments, where an assignment is a mapping of an alternative to exactly one category.

Also implements degenerate cases of multiple categories assignments (where multiple reduces to exactly one), see the note about inheritance in IAssignmentsRead.

An assignments object equals an other one iff they contain the same alternatives assigned to the same categories and the same set of overall categories. The last condition is not redundant as the set of categories may be a superset of the set of categories to which alternatives are assigned. This definition is compatible with the definition of the assignments to multiple categories object.

Method Summary
