Constructor Detail

NegNode

public NegNode(INode[] subt)
Method Detail

eval

public int eval(int[] tuple)
Specified by:
eval in interface ArithmNode

extractResult

public IntDomainVar extractResult(Solver s)
Overrides:
extractResult in class INode
Returns:
a variable that represents the true/false value of the tree belows this node if it is a reified node or its value if it is an arithmetic node

pretty

public String pretty()
Description copied from interface: IPretty
pretty printing of the object. This String is not constant and may depend on the context.

Specified by:
pretty in interface IPretty
Returns:
a readable string representation of the object

isALinearTerm

public boolean isALinearTerm()
Overrides:
isALinearTerm in class INode

computeLinearExpr

public int[] computeLinearExpr(int scope)
Overrides:
computeLinearExpr in class INode
Returns:
the set of coefficients encoding a linear equation
