Constructor Detail

ListGreaterEqualConstraint

public ListGreaterEqualConstraint(N constraintValue)

Creates a Greater-Equal-Than-Number parameter constraint.

That is, all values of the list parameter tested have to be greater than or equal to the specified constraint value.

Parameters:

constraintValue - parameter constraint value

Method Detail

test

public void test(List<N> t)
          throws ParameterException

Checks if all number values of the specified list parameter are greater than or equal to the constraint value. If not, a parameter exception is thrown.

Parameters:

t - Value to be checked whether or not it fulfills the underlying parameter constraint.

Throws:

ParameterException - if the parameter to be tested does not fulfill the parameter constraint

getDescription

public String getDescription(String parameterName)

Description copied from interface: ParameterConstraint

Returns a description of this constraint.

Parameters:

parameterName - the name of the parameter this constraint is used for

Returns:

a description of this constraint
