Interface ObjectFactory<T>

public interface ObjectFactory<T>

A callback interface for the creation of objects that are typically under test by the framework. This interface defines a contract, which must be met. This contract can be asserted by using the ObjectFactory contract assertions. Although this contract mandates five (5) aspects, it is trivial to meet for a typical class. The contract is:

The method newInstanceX() must consistently return new instances. (factory.newInstanceX() == factory.newInstanceX())
must always evaluate to false.

The method newInstanceY() must consistently return new instances. (factory.newInstanceY() == factory.newInstanceY())
must always evaluate to false.

The method newInstanceX() must consistently return instances that are equal to each other.
(factory.newInstanceX().equals(factory.newInstanceX())
must always evaluate to true.

The method newInstanceY() must consistently return instances that are equal to each other.
(factory.newInstanceY().equals(factory.newInstanceY())
must always evaluate to true.

The method newInstanceX() must consistently return instances that are not equal to instances that are returned by newInstanceY().
(factory.newInstanceX().equals(factory.newInstanceY())
must always evaluate to false.
