Constructor Detail

DisplayRdfNode

public DisplayRdfNode(Page page,
              com.hp.hpl.jena.rdf.model.RDFNode root)

Construct a displayable node attached to the given page.

Parameters:

page - The page object

root - The RDF node

DisplayRdfNode

public DisplayRdfNode(Page page,
              com.epimorphics.rdfutil.RDFNodeWrapper root)

Method Detail

setPropertyOrdering

public static void setPropertyOrdering(PropertyOrderingStrategy ordering)

Set the new common strategy for ordering the triples attached to a property.

Parameters:

ordering - The new PropertyOrderingStrategy

propertyOrdering

public static PropertyOrderingStrategy propertyOrdering()

Returns:

The current common property ordering strategy

getDisplayProperties

public List<com.epimorphics.rdfutil.PropertyValue> getDisplayProperties()

Return a list of the triples for this resource which should be displayed, in the order in which they should be displayed.

Returns:

A list of RDF triples in display order

types

public List<com.epimorphics.rdfutil.RDFNodeWrapper> types()

Return the list of types - i.e. values of rdf:type of this resource, sorted into label order.

Returns:

An ordered list of this resources types

labels

public List<com.epimorphics.rdfutil.RDFNodeWrapper> labels()

Return a list of all of the labels for this resource. This will include all of the labelling properties from RDFUtil.labelProps

Returns:

A list of all of the resource's labels

uniqueID

public String uniqueID()

Returns:

A unique ID for this node, e.g. useful for fragment addresses

shortUniqueID

public String shortUniqueID()

Returns:

A short version of the unique ID for this node. Some (minimal) risk of collisions

hasAllProperties

public boolean hasAllProperties(Object... properties)

Returns:

True if this node has all of the given properties

hasAllProperties

public boolean hasAllProperties(List<Object> properties)

withoutNonDisplayTriples

protected List<com.epimorphics.rdfutil.PropertyValue> withoutNonDisplayTriples(List<com.epimorphics.rdfutil.PropertyValue> triples)

Side-effect the given list of triples to remove those that are not to be displayed.

Parameters:

triples - A list of RDF triples from which the non-display triples will be removed.

isNonDisplay

protected boolean isNonDisplay(com.epimorphics.rdfutil.PropertyValue s)

Return true if the given triple should not appear in the list of display triples for a resource. Currently, this equates to the predicate being rdf:type.

Parameters:

s - A triple

Returns:

True if the triple is not part of the resources displayed triples
