Constructor Summary

Node_Variable(java.lang.Object name)

Method Summary

boolean	equals(java.lang.Object other) Nodes only equal other Nodes that have equal labels.
java.lang.String	getName() get a variable nodes name, otherwise die horribly
boolean	isConcrete() Answer true iff this node is concrete, ie not variable, ie URI, blank, or literal.
boolean	isVariable() is this a variable node - overridden in Node_Variable
java.lang.String	toString() Return the N-Triple representation of this node. hedgehog hack: just use the label's string.
java.lang.Object	visitWith(NodeVisitor v) Visit a Node and dispatch on it to the appropriate method from the NodeVisitor v.
