public class PrimaryKeyJoinColumnMetadata
extends RelationalColumnMetadata

INTERNAL: Object to process JPA primary key join columns EclipseLink database fields. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - when loading from annotations, the constructor accepts the metadata accessor this metadata was loaded from. Used it to look up any 'companion' annotation needed for processing. - methods should be preserved in alphabetical order.
