final class GeometryFactories
extends Object

The list of factories available in the current environment. This list depends on which dependencies (JTS, ERSI, etc.) are available at runtime. This list needs to be created in another class than Geometries for avoiding class initialization order problem when a Geometries subclass starts its initialization before Geometries (in such case, an Factory.INSTANCE field may be null).

Note: we can bring this code back into Geometries if JEP 8209964 is implemented.
