Class DCStructureProviderFactory

java.lang.Object
  oracle.adfinternal.model.adapter.generic.DCStructureProviderFactory

public final class DCStructureProviderFactory
extends java.lang.Object

Singleton class that acts as a factory for MetaDataProviders for the given environment(jdev, worplace, etc). This singleton must have the correct DCDefinitionProviderBuilder installed at designtime environment initialization or prior to DataControlStructureProvider construction. the main benefit provided by this class is a level of indirection between runtime and designtime components of the ADF adapter based framework. The TopLink AbstractAdapter and AbstractDefinition implementations need not know about the designtime details (UI and meta data creation) of the environment to create the DataControlStructureProvider. Also a level of abstraction is provided such that multiple persistence technology flavors (OR, EJB, XML) can be incorporated in via their own DataControlStructure and asssociated provider.
