java.lang.Object

org.apache.marmotta.ldpath.api.tests.NodeTest<Node>

org.apache.marmotta.ldpath.model.tests.PathEqualityTest<Node>

All Implemented Interfaces:

NodeFunction<Boolean,Node>, LDPathConstruct<Node>

Direct Known Subclasses:

IsATest

public class PathEqualityTest<Node>
extends NodeTest<Node>

Checks whether a path selector contains a certain node. Used for the syntax construct is e.g. rdf:type is skos:Concept

PathEqualityTest

public PathEqualityTest(NodeSelector<Node> path,
                Node node)

Method Detail

accept

public boolean accept(RDFBackend<Node> rdfBackend,
             Node context,
             Node candidate)
               throws IllegalArgumentException

Apply the function to the list of nodes passed as arguments and return the result as type T. Throws IllegalArgumentException if the function cannot be applied to the nodes passed as argument or the number of arguments is not correct.

Specified by:

accept in class NodeTest<Node>

Parameters:

args - a nested list of KiWiNodes

Returns:

Throws:

IllegalArgumentException

getPathExpression

public String getPathExpression(NodeBackend<Node> rdfBackend)

Return the representation of the NodeFunction or NodeSelector in the RDF Path Language

Parameters:

rdfBackend -

Returns:

getSignature

public String getSignature()

A string describing the signature of this node function, e.g. "fn:content(uris : Nodes) : Nodes". The syntax for representing the signature can be chosen by the implementer. This method is for informational purposes only.

Returns:

getDescription

public String getDescription()

A short human-readable description of what the node function does.

Returns:

equals

public boolean equals(Object o)

Overrides:

hashCode

public int hashCode()

Overrides:

hashCode in class Object
