- All Implemented Interfaces:
- java.io.Serializable
- 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.
