equals, getOrderNumber, hashCode, nextHash, setOrderNumber

Modifier and Type	Method	Description
boolean	equals(Object obj)
int	getOrderNumber()	Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order.
final int	hashCode()
static int	nextHash()	I know this is theoretically bad.
void	setOrderNumber(int orderNumber)	Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order.

Methods inherited from class NodeWithNumber

getGraphNodeId, setGraphNodeId

Modifier and Type	Method	Description
int	getGraphNodeId()	A non-negative integer which serves as an identifier for this node in it's "dominant" graph.
void	setGraphNodeId(int i)
