Interface EdgeLabelMapping

All Known Implementing Classes:

CompositeEdgeLabelMappingImpl, EdgeLabelMappingImpl_AllToURIs, EdgeLabelMappingImpl_RegexMatchToURIs, EdgeLabelMappingImpl_SingleMatchToURI

public interface EdgeLabelMapping

This interface captures the notion of an edge label mapping that is part of the notion of an LPG-to-RDF configuration, and that such an edge Label mapping is an injective function from edge labels in LPGs to IRIs nodes as can occur in RDF graphs. This interface contains the functions: -map: map String of edge labels to IRIs edge Labels -unmap: map IRIs edge labels to String -isPossibleResult: Check if the given RDF term is in the image of this edge label mapping

Method Summary

Modifier and Type	Method	Description
boolean	isPossibleResult(org.apache.jena.graph.Node node)	Check if the given RDF term is in the image of this edgeLabel mapping and, thus, may be one of the RDF terms returned by the map(String) function for some String.
org.apache.jena.graph.Node	map(String label)	Returns a URI edge label (in the form of a Jena Node object) for the given String.
String	unmap(org.apache.jena.graph.Node node)	Returns the String that corresponds to the given RDF term.

Method Details

map

org.apache.jena.graph.Node map(String label)

Returns a URI edge label (in the form of a Jena Node object) for the given String. It applies this edge label mapping to the given String.

unmap

String unmap(org.apache.jena.graph.Node node)

Returns the String that corresponds to the given RDF term. It applies the inverse of this edge Label mapping to the given RDF term (which is assumed to be an IRI) in order to obtain the corresponding String.

isPossibleResult

boolean isPossibleResult(org.apache.jena.graph.Node node)

Check if the given RDF term is in the image of this edgeLabel mapping and, thus, may be one of the RDF terms returned by the map(String) function for some String.
