MappedKeyMapAccessor

public class ManyToManyAccessor
extends CollectionAccessor

INTERNAL: A many to many relationship accessor. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - any metadata mapped from XML to this class must be handled in the merge method. (merging is done at the accessor/mapping level) - any metadata mapped from XML to this class must be initialized in the initXMLObject method. - methods should be preserved in alphabetical order.
