ListEachNumberConstraint

public ListEachNumberConstraint(AbstractNumberConstraint constraint)

Constructor.

Parameters:

constraint - Constraint to apply to all elements

Method Detail

addConstraint

public void addConstraint(AbstractNumberConstraint constraint)

Add a constraint to this operator.

Parameters:

constraint - Constraint

test

public void test(T t)
          throws ParameterException

Description copied from interface: ParameterConstraint

Checks if the value t of the parameter to be tested fulfills the parameter constraint. If not, a parameter exception is thrown.

Specified by:

test in interface ParameterConstraint<T>

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 java.lang.String getDescription(java.lang.String parameterName)

Description copied from interface: ParameterConstraint

Returns a description of this constraint.

Specified by:

getDescription in interface ParameterConstraint<T>

Parameters:

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

Returns:

a description of this constraint
