All Implemented Interfaces:

LoadSecondary, PrimaryTable, StorePrimary, StoreSecondary

Direct Known Subclasses:

BlobMapping, ClobMapping

public abstract class LobMapping

extends FieldMapping

implements LoadSecondary, StorePrimary, StoreSecondary, PrimaryTable

Represents the mapping of a locator object column in the owning class' primary table. Locator objects are loaded and stored as secondary mappings for efficiency and due to the special handling needed to deal with them.
