Node_Variable

public Node_Variable(String name)

Initialise this Node_Variable from a string name, which becomes wrapped in a VariableName.

Method Details

isConcrete

public boolean isConcrete()

Description copied from class: Node

Answer true iff this node is concrete, meaning a node that is data in an RDF Graph.

Specified by:

isConcrete in class Node

getName

public String getName()

get a variable nodes name, otherwise die horribly

Overrides:

getName in class Node

visitWith

public Object visitWith(NodeVisitor v)

Description copied from class: Node

Visit a Node and dispatch on it to the appropriate method from the NodeVisitor v.

Specified by:

visitWith in class Node

Parameters:

v - the visitor to apply to the node

Returns:

the value returned by the applied method

isVariable

public boolean isVariable()
