FallbackAuthorityFactory
protected FallbackAuthorityFactory(AuthorityFactory primary, AuthorityFactory fallback)
Wraps a primary and a fallback authority factories.This constructor is protected because subclasses must declare which of the
DatumAuthorityFactory
,CSAuthorityFactory
,CRSAuthorityFactory
andCoordinateOperationAuthorityFactory
interfaces they choose to implement.- Parameters:

- The primary factory.fallback
- The factory to use as a fallback if the primary factory failed.- See Also:
