evaluate
public byte evaluate(BitVectorVariable lhs, BitVectorVariable[] rhs) throws IllegalArgumentException Description copied from class:AbstractOperator
Evaluate this equation, setting a new value for the left-hand side.- Specified by:
evaluate
in classAbstractOperator<BitVectorVariable>
- Returns:
- a code that indicates: 1) has the lhs value changed? 2) has this equation reached a fixed-point, in that we never have to evaluate the equation again, even if rhs operands change?
- Throws:
IllegalArgumentException
