getSubVisitor

public QueryVisitor getSubVisitor(BooleanClause.Occur occur,
 Query parent)

Description copied from class: QueryVisitor

Pulls a visitor instance for visiting child clauses of a query

The default implementation returns this, unless occur is equal to BooleanClause.Occur.MUST_NOT in which case it returns QueryVisitor.EMPTY_VISITOR

Overrides:

getSubVisitor in class QueryVisitor

Parameters:

occur - the relationship between the parent and its children

parent - the query visited

consumeTerms

public void consumeTerms(Query query,
 Term... terms)

Description copied from class: QueryVisitor

Called by leaf queries that match on specific terms

Overrides:

consumeTerms in class QueryVisitor

Parameters:

query - the leaf query

terms - the terms the query will match on

visitLeaf

public void visitLeaf(Query query)

Description copied from class: QueryVisitor

Called by leaf queries that do not match on terms

Overrides:

visitLeaf in class QueryVisitor

Parameters:

query - the query

apply

public QueryTree apply(TermWeightor termWeightor)

Specified by:

apply in interface Function<TermWeightor,QueryTree>
