The default implementation always returns null
, since there is no database
connected to a DefaultCoordinateOperationFactory
instance. In other words,
the default implementation is "standalone": it tries to figure out transformation
paths by itself. Subclasses should override this method if they can fetch a more
accurate operation from some database. The mean subclass doing so is
AuthorityBackedFactory

geographic from/to projected CRS
operations). This method is not invoked for synthetic CRS generated by
createOperationStep(...)
