Class GraphBlendingIterator

java.lang.Object

won.utils.goals.GraphBlendingIterator

All Implemented Interfaces:

java.util.Iterator<org.apache.jena.rdf.model.Model>

public class GraphBlendingIterator
extends java.lang.Object
implements java.util.Iterator<org.apache.jena.rdf.model.Model>

Iterator class that iterates over all possible models that could be a valid result from blending two input models. Blending of two subject resource URIs is defined to be valid if there exists at least one statement in each input model with the same objects and predicates for these subjects. Resource URIs of the input models are only considered for blending if they are part of a "variable uri name space" which is passed in the constructor of this class together with the two input models for blending.

Constructor Detail

GraphBlendingIterator

public GraphBlendingIterator(org.apache.jena.rdf.model.Model dataModel1,
                             org.apache.jena.rdf.model.Model dataModel2,
                             java.lang.String variableUriPrefix,
                             java.lang.String blendingUriPrefix)

Initialize the blending iterator

Parameters:

dataModel1 - first input model for blending

dataModel2 - second input model for blending

variableUriPrefix - uri prefix defines which resource URIs are considered for blending

blendingUriPrefix - uri prefix that is used to generate the result URIs of blended resources
