Class EntityFactoryDefault

java.lang.Object

bridge.reps.entities.EntityFactoryDefault

All Implemented Interfaces:

EntityFactory

public class EntityFactoryDefault
extends java.lang.Object
implements EntityFactory

This implementation of EntityFactory simply calls the appropriate Entity/Function/Relation/Sequence constructor, and returns the resulting Entity. No further configuration is performed. This class implements the Singleton design pattern, because it is immutable and nonconfigurable. To get an instance of this class, use EntityFactoryDefault.getInstance().
