Interface IVariable<T extends IVariable>

All Superinterfaces:

INodeWithNumber

All Known Implementing Classes:

AbstractIntStackMachine.MachineState, AbstractVariable, BitVectorVariable, BooleanVariable, IntSetVariable, PointsToSetVariable, TypeVariable

public interface IVariable<T extends IVariable>
extends INodeWithNumber

Represents a single variable in a fixed-point iterative system.

Method Summary

void	copyState(T v) Set this variable to have the same state as another one
int	getOrderNumber() Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order.
void	setOrderNumber(int i) Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order.

Method Detail

getOrderNumber

int getOrderNumber()

Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order. It might be cleaner to hold this on the side, but we cannot tolerate any extra space. TODO: consider moving this functionality to a subinterface?

Returns:

a number used to order equation evaluation

setOrderNumber

void setOrderNumber(int i)

Variables must allow the solver implementation to get/set an order number, which the solver uses to control evaluation order. It might be cleaner to hold this on the side, but we cannot tolerate any extra space. TODO: consider moving this functionality to a subinterface?

copyState

void copyState(T v)

Set this variable to have the same state as another one
