Method Details

getSingleOptionalProperty

public static org.apache.jena.rdf.model.RDFNode getSingleOptionalProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Based on the assumption that the given resource may have a single value for the given property, this function returns either this value or null, depending on whether the resource has such a value. If the resource has multiple values for the property, an IllegalArgumentException is thrown.

getSingleOptionalResourceProperty

public static org.apache.jena.rdf.model.Resource getSingleOptionalResourceProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource may have a single value for the given property and, if so, this value is a resource (not a literal). Based on this assumption, this function returns either the literal or null, depending on whether the resource has such a value. If the value is not a resource or the resource has multiple values for the property, an IllegalArgumentException is thrown.

getSingleOptionalLiteralProperty

public static org.apache.jena.rdf.model.Literal getSingleOptionalLiteralProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource may have a single value for the given property and, if so, this value is a literal. Based on this assumption, this function returns either the literal or null, depending on whether the resource has such a value. If the value is not a literal or the resource has multiple values for the property, an IllegalArgumentException is thrown.

getSingleOptionalProperty_XSDString

public static String getSingleOptionalProperty_XSDString(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource may have a single value for the given property and, if so, this value is an xsd:string literal. Based on this assumption, this function returns either the string of this literal or null, depending on whether the resource has such a value. If the value is not an xsd:string literal or the resource has multiple values for the property, an IllegalArgumentException is thrown.

getSingleOptionalProperty_XSDURI

public static URI getSingleOptionalProperty_XSDURI(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource may have a single value for the given property and, if so, this value is an xsd:anyURI literal. Based on this assumption, this function returns either the URI of this literal or null, depending on whether the resource has such a value. If the value is not an xsd:anyURI literal, the lexical form of the literal cannot be converted into a URI, or the resource has multiple values for the property, an IllegalArgumentException is thrown.

getSingleMandatoryProperty

public static org.apache.jena.rdf.model.RDFNode getSingleMandatoryProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Based on the assumption that the given resource has a single value for the given property, this function returns this. An IllegalArgumentException is thrown if the resource does not have any value for the property or it has multiple values for the property.

getSingleMandatoryResourceProperty

public static org.apache.jena.rdf.model.Resource getSingleMandatoryResourceProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource has a single value for the given property and this value is a resource (not a literal). Based on this assumption, this function returns this literal. An IllegalArgumentException is thrown if the value is not a resource, the resource does not have any value for the property, or it has multiple values for the property.

getSingleMandatoryLiteralProperty

public static org.apache.jena.rdf.model.Literal getSingleMandatoryLiteralProperty(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource has a single value for the given property and this value is a literal. Based on this assumption, this function returns this literal. An IllegalArgumentException is thrown if the value is not a literal, the resource does not have any value for the property, or it has multiple values for the property.

getSingleMandatoryProperty_XSDString

public static String getSingleMandatoryProperty_XSDString(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource has a single value for the given property and this value is an xsd:string literal. Based on this assumption, this function returns the string of this literal. An IllegalArgumentException is thrown if the value is not an xsd:string literal, the resource does not have any value for the property, or it has multiple values for the property.

getSingleMandatoryProperty_XSDURI

public static URI getSingleMandatoryProperty_XSDURI(org.apache.jena.rdf.model.Resource r,
 org.apache.jena.rdf.model.Property p)

Assumes that the given resource has a single value for the given property and this value is an xsd:anyURI literal. Based on this assumption, this function returns the URI of this literal. An IllegalArgumentException is thrown if the value is not an xsd:anyURI literal, the lexical form of the literal cannot be converted into a URI, the resource does not have any value for the property, or it has multiple values for the property.
