hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object

toString

public String toString()

inline

public static NodeId inline(org.apache.jena.graph.Node node)

Encode a node as an inline literal. Return null if it can't be done

hasInlineDatatype

public static boolean hasInlineDatatype(org.apache.jena.graph.Node node)

Return true if this node has a datatype that looks like it is inlineable. The node may still be out of range (e.g. very large integer). Only inline(Node)->NodeId can determine that.

isInline

public static boolean isInline(NodeId nodeId)

extract

public static org.apache.jena.graph.Node extract(NodeId nodeId)

Decode an inline nodeID, return null if not an inline node

isConcrete

public final boolean isConcrete()

isConcrete

public static final boolean isConcrete(NodeId nodeId)

isAny

public static final boolean isAny(NodeId nodeId)

isDoesNotExist

public static final boolean isDoesNotExist(NodeId nodeId)
