Package com.im.df.impl.db

Class DBRelationDataProviderImpl

java.lang.Object

com.im.df.impl.db.DBRelationDataProviderImpl

All Implemented Interfaces:

com.im.df.api.dml.DFRelationDataProvider

public class DBRelationDataProviderImpl
extends Object
implements com.im.df.api.dml.DFRelationDataProvider

TODO - P2 [Svata]: Create subclasses for individual relationship types. Then discard the ugly IFs on relationship type and replace by abstract methods overriden by per-relation-type subclasses TODO - P1 [Svata]: the doClear method should check that all the detail rows are really linked to the prescribed master. ideally a queryForIDs plus intersection of the requested vs. actual set of detail entities. Then events would be fired that reflect the real operation.
