Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Internal Calendar component. Resolves transfers of conflicting solemnities.

For any day Temporale has a Celebration. Often Sanctorale has one (or more), too. Calendar handles these conflicts, in most cases by throwing away all the proposed Celebrations except of the one of highest rank. But when there are two conflicting solemnities, one is celebrated on the given day and the less lucky one must be transferred to another day. However, not all days are valid as targets of solemnity transfer.
