Constructor Detail

LessEqualConstraint

public LessEqualConstraint(Number constraintValue)

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

That is, the value of the appropriate number parameter has to be less equal than the given constraint value.

Parameters:

constraintValue - the constraint value

Method Detail

test

public void test(Number t)
          throws ParameterException

Checks if the number value given by the number parameter is less equal than 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
