java.lang.Object

org.aksw.jenax.facete.treequery2.impl.RootedFacetTraversableBase<NodeQuery,ConstraintNode<NodeQuery>>

org.aksw.jenax.facete.treequery2.impl.ConstraintNodeImpl

All Implemented Interfaces:

ConstraintNode<NodeQuery>, FacetTraversable<ConstraintNode<NodeQuery>>, RootedFacetTraversable<NodeQuery,ConstraintNode<NodeQuery>>, Sortable<ConstraintNode<NodeQuery>>, org.aksw.jenax.path.core.HasFacetPath

public class ConstraintNodeImpl
extends RootedFacetTraversableBase<NodeQuery,ConstraintNode<NodeQuery>>
implements ConstraintNode<NodeQuery>

This implementation features support for traversals along facet paths as well as setting constraints on the paths.

ConstraintNodeImpl

public ConstraintNodeImpl(NodeQuery root,
 org.aksw.jenax.path.core.FacetPath path)

Method Details

var

public org.apache.jena.sparql.core.Var var()

Description copied from interface: ConstraintNode

A variable name that uniquely identifies this node in the query model Can be seen as a field id.

Specified by:

var in interface ConstraintNode<NodeQuery>

getScopedFacetPath

public ScopedFacetPath getScopedFacetPath()

getParent

public ConstraintNode<NodeQuery> getParent()

Specified by:

getParent in interface FacetTraversable<ConstraintNode<NodeQuery>>

getOrCreateChild

public ConstraintNodeImpl getOrCreateChild(org.aksw.jenax.path.core.FacetStep step)

Description copied from interface: FacetTraversable

Returns null if there is no child reachable with the given step.

Specified by:

getOrCreateChild in interface FacetTraversable<ConstraintNode<NodeQuery>>

enterConstraints

public ConstraintFacade<ConstraintNode<NodeQuery>> enterConstraints()

Specified by:

enterConstraints in interface ConstraintNode<NodeQuery>

asJenaNode

public org.apache.jena.graph.Node asJenaNode()

Wrap this node as a Jena node so that it can be used as a 'pseudo-variable' in expressions. To substitute NodeQuery references in expressions, apply a node transform using NodeFacetPath.createNodeTransform(pathTransform).

Specified by:

asJenaNode in interface ConstraintNode<NodeQuery>

sort

public ConstraintNode<NodeQuery> sort(int sortDirection)

Description copied from interface: Sortable

Updates or adds the first sort condition of this query node's variable in the list of sort conditions

Specified by:

sort in interface Sortable<ConstraintNode<NodeQuery>>

getSortDirection

public int getSortDirection()

Description copied from interface: Sortable

Returns the direction of the first sort condition that matches this query node's variable

Specified by:

getSortDirection in interface Sortable<ConstraintNode<NodeQuery>>

availableValues

public FacetedDataQuery<org.apache.jena.rdf.model.RDFNode> availableValues()

Specified by:

availableValues in interface ConstraintNode<NodeQuery>

remainingValues

public FacetedDataQuery<org.apache.jena.rdf.model.RDFNode> remainingValues()

Specified by:

remainingValues in interface ConstraintNode<NodeQuery>

createValueQuery

public FacetedDataQuery<org.apache.jena.rdf.model.RDFNode> createValueQuery(boolean applySelfConstraints)
