All Implemented Interfaces:

public class UnknownRelationException
extends PQFTranslationException

Exception indicating that a relation was not recognised. At compilation time, we accept any syntactically valid relation; but when rendering a tree out as PQF, we need to translate the relations into sets of Type-1 query attributes. If we can't do that, because the PQF configuration doesn't know about a relation, we throw one of these babies.
