@ThreadSafe
public class ReferencingFactory
extends Factory
implements Factory

Base class for all factories in the referencing module. Factories can be grouped in two categories:

• Authority factories creates objects from a compact string defined by an authority. These classes are working as "builders": they hold the definition or recipes used to construct an object.

• Object factories allows applications to make objects that cannot be created by an authority factory. This factory is very flexible, whereas the authority factory is easier to use. These classes are working as "Factories": they provide a series of create methods that can be used like a constructor.

Method Detail

getVendor

public Citation getVendor()

Returns the vendor responsible for creating this factory implementation. Many implementations from different vendors may be available for the same factory interface.
