Method Details

keyToString

protected String keyToString()

Specified by:

keyToString in class KeyedEnumerablePConstraint<Object>

getVariable

public PVariable getVariable()

Since:

1.7

getFunctionalDependencies

public Map<Set<PVariable>, Set<PVariable>> getFunctionalDependencies(IQueryMetaContext context)

Description copied from interface: PConstraint

A (preferably minimal) cover of known functional dependencies between variables.

Specified by:

getFunctionalDependencies in interface PConstraint

Overrides:

getFunctionalDependencies in class BasePConstraint

Returns:

non-trivial functional dependencies in the form of {variables} --> {variables}, where dependencies with the same lhs are unified.
