All Implemented Interfaces:

Factory

Deprecated. Will be replaced by StrictReturnsNullFactory, when available

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

Generic factory class creating objects based on Specifications.

It is named strict because it rather 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.

In addition, this factory is kind of dumb, as it demands that a constructor with all necessary parameters is available. That is why it is deprecated on arrival.
