Class Constraint

java.lang.Object

de.rwth.swc.coffee4j.model.constraints.Constraint

public class Constraint
extends java.lang.Object

Defines a constraint for combinatorial testing as a collection of parameters names and a function which can check whether any given value assignment for those parameters is valid or not according to some logic defined by the function.

Constructor Detail

Constraint

public Constraint(java.lang.String name,
                  java.util.List<java.lang.String> parameterNames,
                  ConstraintFunction constraintFunction)

Constraint

public Constraint(java.lang.String name,
                  java.util.List<java.lang.String> parameterNames,
                  ConstraintFunction constraintFunction,
                  ConstraintStatus constraintStatus)

Creates a new constraint. It is most efficient if only the parameters really involved and not additional ones are given.

Parameters:

name - a name to improve readability without further semantics

parameterNames - the names of all involved parameters. Must not be, or contain null, or be empty

constraintFunction - the function by which the values for the parameters are constrained. Must not be null

constraintStatus - status is either Unknown or Correct which is related to conflict detection

getConstraintFunction
