Constructor Detail

UnArExpression

public UnArExpression(ArExpression.Operator op,
                      ArExpression exp)

Builds a unary expression

Parameters:

op - operator

exp - an arithmetic expression

Method Detail

getModel

public Model getModel()

Description copied from interface: ArExpression

Return the associated model

Specified by:

getModel in interface ArExpression

Returns:

a Model object

getOp

public ArExpression.Operator getOp()

getNoChild

public int getNoChild()

Specified by:

getNoChild in interface ArExpression

Returns:

the child of this expression, or null if thid

getExpressionChild

public ArExpression[] getExpressionChild()

Specified by:

getExpressionChild in interface ArExpression

Returns:

the child of this expression, or null if thid

intVar

public IntVar intVar()

Specified by:

intVar in interface ArExpression

Returns:

the arithmetic expression as an IntVar. If necessary, it creates intermediary variable and posts intermediary constraints

ieval

public int ieval(int[] values,
                 Map<IntVar,Integer> map)

Specified by:

ieval in interface ArExpression

Parameters:

values - int values to evaluate

map - mapping between variables of the topmost expression and position in values

Returns:

an evaluation of this expression with a tuple

toString
