Class EnrollmentSnapshot

java.lang.Object
  com.clra.rowing.EnrollmentSnapshot

All Implemented Interfaces:: java.io.Serializable

public class EnrollmentSnapshot
extends java.lang.Object
implements java.io.Serializable

Read-only information about enrollment of a member in a rowing session. Unlike a Participant entity, which is non-null only if a member is signed up for a rowing session, an enrollment instance is guaranteed to be non-null regardless of whether a member is signed up in a rowing session. An enrollment instance is a derived view that doesn't correspond to a persistent object in the database.

An enrollment is composed of a member_id, a rowing_id, and a participant_id. The member_id and rowing_id must be non-null. The participant_id is non-null only if the member has signed up for the rowing session. In addition to these primary keys, an enrollment object caches some frequently needed data from the member, rowing session and participant entities.
