getDeducedVariables
public java.util.Set<PVariable> getDeducedVariables()
Description copied from interface:PConstraint
The set of variables whose potential values can be enumerated (once all non-deduced variables have known values).
-
getFunctionalDependencies
public java.util.Map<java.util.Set<PVariable>,java.util.Set<PVariable>> getFunctionalDependencies(IQueryMetaContext context)
Description copied from interface:PConstraint
A (preferably minimal) cover of known functional dependencies between variables.- Specified by:
getFunctionalDependencies
in interfacePConstraint
- Overrides:
getFunctionalDependencies
in classBasePConstraint
- Returns:
- non-trivial functional dependencies in the form of {variables} --> {variables}, where dependencies with the same lhs are unified.
