parameters

private List<? extends Parameter<?,?>> parameters

List of number parameters to be checked.

Constructor Detail

NoDuplicateValueGlobalConstraint

public NoDuplicateValueGlobalConstraint(List<? extends Parameter<?,?>> parameters)

Constructs a Not-Equal-Value global parameter constraint. That is, the elements of a list of number parameters are not allowed to have equal values.

Parameters:

parameters - list of number parameters to be tested

NoDuplicateValueGlobalConstraint

public NoDuplicateValueGlobalConstraint(Parameter<?,?>... parameters)

Constructs a Not-Equal-Value global parameter constraint. That is, the elements of a list of number parameters are not allowed to have equal values.

Parameters:

parameters - list of number parameters to be tested

Method Detail

test

public void test()
          throws ParameterException

Checks if the elements of the list of number parameters do have different values. If not, a parameter exception is thrown.

Specified by:

test in interface GlobalParameterConstraint

Throws:

ParameterException - if the parameters don't satisfy the parameter constraint.

getDescription

public String getDescription()

Description copied from interface: GlobalParameterConstraint

Returns a description of this global constraint.

Specified by:

getDescription in interface GlobalParameterConstraint

Returns:

a description of this global constraint
