Method Summary

Modifier and Type	Method	Description
static final List<CDTValue>	checkAndGetList(org.apache.jena.graph.Node n)	Calls ensureListLiteral(Node) first, and getList(Node) afterwards.
static final List<CDTValue>	checkAndGetList(NodeValue nv)
static final Map<CDTKey,CDTValue>	checkAndGetMap(org.apache.jena.graph.Node n)	Calls ensureMapLiteral(Node) first, and getMap(Node) afterwards.
static final Map<CDTKey,CDTValue>	checkAndGetMap(NodeValue nv)
static final org.apache.jena.graph.Node	createNode(List<CDTValue> list)	Creates a Node with a cdt:List literal that represents the given list.
static final org.apache.jena.graph.Node	createNode(Map<CDTKey,CDTValue> map)	Creates a Node with a cdt:Map literal that represents the given map.
static final NodeValue	createNodeValue(List<CDTValue> list)	Creates a NodeValue with a cdt:List literal that represents the given list.
static final NodeValue	createNodeValue(Map<CDTKey,CDTValue> map)	Creates a NodeValue with a cdt:Map literal that represents the given map.
static final void	ensureListLiteral(org.apache.jena.graph.Node n)	Uses CompositeDatatypeList.isListLiteral(Node) to check whether the given node is a cdt:List literal and throws an exception if not.
static final void	ensureMapLiteral(org.apache.jena.graph.Node n)	Uses CompositeDatatypeMap.isMapLiteral(Node) to check whether the given node is a cdt:Map literal and throws an exception if not.
static final List<CDTValue>	getList(org.apache.jena.graph.Node n)	Assumes that the given node is a cdt:List literal and uses CompositeDatatypeList.getValue(LiteralLabel) to get the list.
static final Map<CDTKey,CDTValue>	getMap(org.apache.jena.graph.Node n)	Assumes that the given node is a cdt:Map literal and uses CompositeDatatypeMap.getValue(LiteralLabel) to get the map.

Method Details

ensureListLiteral

public static final void ensureListLiteral(org.apache.jena.graph.Node n)
                                    throws ExprEvalException

Uses CompositeDatatypeList.isListLiteral(Node) to check whether the given node is a cdt:List literal and throws an exception if not.

Throws:

ExprEvalException

ensureMapLiteral

public static final void ensureMapLiteral(org.apache.jena.graph.Node n)
                                   throws ExprEvalException

Uses CompositeDatatypeMap.isMapLiteral(Node) to check whether the given node is a cdt:Map literal and throws an exception if not.

Throws:

ExprEvalException

getList

public static final List<CDTValue> getList(org.apache.jena.graph.Node n)
                                    throws ExprEvalException

Assumes that the given node is a cdt:List literal and uses CompositeDatatypeList.getValue(LiteralLabel) to get the list. Throws an ExprEvalException if a DatatypeFormatException is thrown by CompositeDatatypeList.getValue(LiteralLabel).

Throws:

ExprEvalException

getMap

public static final Map<CDTKey,CDTValue> getMap(org.apache.jena.graph.Node n)
                                         throws ExprEvalException

Assumes that the given node is a cdt:Map literal and uses CompositeDatatypeMap.getValue(LiteralLabel) to get the map. Throws an ExprEvalException if a DatatypeFormatException is thrown by CompositeDatatypeMap.getValue(LiteralLabel).

Throws:

ExprEvalException

checkAndGetList

public static final List<CDTValue> checkAndGetList(org.apache.jena.graph.Node n)

Calls ensureListLiteral(Node) first, and getList(Node) afterwards.

Throws:

ExprEvalException

checkAndGetMap

Calls ensureMapLiteral(Node) first, and getMap(Node) afterwards.

Throws:

ExprEvalException

checkAndGetList

public static final List<CDTValue> checkAndGetList(NodeValue nv)
                                            throws ExprEvalException

Throws:
