Interface FactoryUsingVolatileDependencies

All Superinterfaces:

Factory

Deprecated.

This class should be a marker interface instead of an AbstractFactory subclass. We will make this change in a future version. When this change is done, AllAuthoritiesFactory should implement this interface.

public interface FactoryUsingVolatileDependencies
extends Factory

A factory that can not determines all its dependencies at construction time. Because this factory may creates new factories at any time, it must keep all user-supplied hints. The general contract of #hints said that we can't use this field for creating new factories. But instances of this classe are special cases where we can, because this class retains all user-supplied hints.

Extends this class only if you really need to keep all user-supplied hints, because doing so has a cost:

• FactoryRegistry is less likely to reuse existing factory instances, because any value found in #hints that do not agree with a user-supplied hint will cause FactoryRegistry to discarts this instance, even if the hint was actually irrelevant to this factory.

• The user-supplied hints may contain references to big objects (for example a coordinate transform backed by a grid), and some of them may not be relevant to this factory. Retaining all hints will prevents their garbage collection.
