Method Detail

isProperty

boolean isProperty()

getNameSpace

java.lang.String getNameSpace()

Returns the namespace associated with this resource if it is a URI, else return null.

The namespace is suitable for use with localname in in RDF/XML. XML does not allow QNames to start with a digit and this method reflects that restriction in the values for namespace and localname.

See functions in SplitIRI for other split algorithms.

Specified by:

getNameSpace in interface Resource

Returns:

The namespace for this resource or null.

inModel

Property inModel(Model m)

Override RDFNode.inModel() to produce a staticly-typed Property in the given Model.

Specified by:

inModel in interface RDFNode

Specified by:

inModel in interface Resource

Parameters:

m - a model to move the node to

Returns:

this, if it's already in m (or no model), a copy in m otherwise

getLocalName

java.lang.String getLocalName()

Returns the localname of this resource within its namespace if it is a URI else null.

Note: XML requires QNames to start with a letter, not a digit, and this method reflects that restriction.

See functions in SplitIRI.

Specified by:

getLocalName in interface Resource

Returns:

The localname of this property within its namespace.

getOrdinal

int getOrdinal()

Returns the ordinal value of a containment property.

RDF containers use properties of the form _1, _2, _3 etc to represent the containment relationship between the container and the objects it contains. When invoked on such a containment property, this method returns the integer part of the property name. When invoked on other properties, it returns 0.

Returns:

The ordinal value of a containment property, or 0 otherwise.
