edu.umass.cs.surveyman.analyses.rules.BranchConsistency

public class BranchConsistency
extends AbstractRule

Ensures that branch rules are obeyed on a per-block basis:

• NONE: If a block is marked as having no branch target, then it should not have a branch question saved.
• ALL: If a block is marked as ALL, then three requirements must be met:
  1. All questions are branch questions.
  2. All questions have equal number of options.
  3. All questions have equivalent branch maps.
• ONE: If a block is marked as ONE, then we make sure there are no other branch questions and that the stored branch question is the appropriate one.
