Constructor Detail

LessGlobalConstraint

public LessGlobalConstraint(NumberParameter<T> first,
                    NumberParameter<T> second)

Creates a Less-Than global parameter constraint. That is the value of the first number parameter given has to be less than the value of the second number parameter given.

Parameters:

first - first number parameter

second - second number parameter

Method Detail

test

public void test()
          throws ParameterException

Checks if the value of the first number parameter is less than the value of the second number parameter. 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
