The FirstMatchCodeGroup class is a concrete subclass of the CodeGroup class. Members of a FirstMatchCodeGroup are tested for membership against its child code groups in order. After qualifying for membership to a child group, the comparison stops, which means that the order of the children is important. The final permission set granted by the FirstMatchCodeGroup is the union of its permission set and at most one of its children.
