Method Summary

boolean	isFrozen() Answer true iff this node is "frozen", ie its value is fixed, when it is encountered; that is, it is not a Bind or JustBound node.
boolean	match(Domain d, Node X) Answer true iff this QueryNode matches, in the context of the binding Domain d, the node x.
boolean	matchOrBind(Domain d, Node x) Optimisation: the action to be performed when matching a just-bound variable or binding a newly-bound variable, or nothing for any other kind of QueryNode.
boolean	mustMatch() Answer true iff this QueryNode must be used in a triple-match of its owning QueryTriple.
String	toString() Return a handy string representation for debugging purposes.
