All Implemented Interfaces:

java.io.Serializable

public class AmbiguousMappingException
extends LQPException

Raised when the mapping defined in the RenameMap introduces ambiguity. For example with mapping defined as (id, id) <-> (id, ident) going from ident->id will introduce ambiguity when for example we want to rename attribute used in a predicate like ident<3. This usually happens when we move the RENAME operator up and down the tree.
