 PQuery query,
 PVariable resultVariable)

Method Details

getDeducedVariables

public 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 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.

protected void doDoReplaceVariables(PVariable obsolete,
 PVariable replacement)

Specified by:

doDoReplaceVariables in class PatternCallBasedDeferred

getCandidateQuantifiedVariables

protected Set<PVariable> getCandidateQuantifiedVariables()

Specified by:

getCandidateQuantifiedVariables in class PatternCallBasedDeferred

toStringRest

protected String toStringRest()

Specified by:

toStringRest in class BasePConstraint

getResultVariable

public PVariable getResultVariable()
