All Implemented Interfaces:

java.io.Serializable

public class UnknownQualifierException

extends PQFTranslationException

Exception indicating that a qualifier was not recognised. At compilation time, we accept any syntactically valid qualifier; but when rendering a tree out as PQF, we need to translate the qualifiers 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.
