Class StrictReturnsNullFactory<T>

java.lang.Object
  net.sourceforge.domian.factory.StrictReturnsNullFactory<T>

All Implemented Interfaces:

Factory

public final class StrictReturnsNullFactory<T>
extends java.lang.Object
implements Factory

Generic factory class creating objects based on Specifications.

It is named strict because it returns null rather than a possible imperfect object. If the specification contains ambiguous data, or is somehow missing data, the factory will not construct any object.

Returns null object creation strategy means that the factory will silently return null when the first show-stopping obstacle occurs.
