RelationToManyTableFieldStrategy	Maps a set of related objects through an association table.
StateComparisonVersionStrategy	Uses a state image to determine whether concurrency violations take place.
StateComparisonVersionStrategy.CustomUpdate	Row implementation we use to pass to versionable mappings so they can set up the where conditions we need to add to update statements.
StoreCollectionFieldStrategy	Base class for strategies that are stored as a collection, even if their field value is something else.
StringFieldStrategy	Direct mapping from a string value to a column.
SubclassJoinDiscriminatorStrategy	Discriminator strategy that outer joins to all possible subclass tables to determine the class of an instance.
SuperclassDiscriminatorStrategy	Discriminator strategy that delegates to superclass discriminator.
