ValueNode |
changeToCNF(boolean underTopAndNode)
Finish putting an expression into conjunctive normal
form.

init(java.lang.Object leftOperand,
java.lang.Object rightOperand)
Initializer for an OrNode
|
(package private) void |
postBindFixup()
Do bind() by hand for an AndNode that was generated after bind(),
eg by putAndsOnTop().
