getParent

public AtomicQuery getParent()

establishRelation

public void establishRelation(AtomicQuery aq)

establishes parent-child (if there is one) relation between this and aq query the relation expresses the relative level of specificity between queries with the parent being more specific

Parameters:

subs - IdPredicates of variables

Returns:

Materialised answers

unify

public void unify(Map<String,String> unifiers)

Description copied from class: Query
