Class LessEqualConstraint

  • All Implemented Interfaces:
    ParameterConstraint<java.lang.Number>
    public class LessEqualConstraint
extends AbstractNumberConstraint
    Represents a Less-Equal-Than-Number parameter constraint. The value of the number parameter (NumberParameter) tested has to be less equal than the specified constraint value.

      • LessEqualConstraint

        public LessEqualConstraint​(java.lang.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

      • LessEqualConstraint

        public LessEqualConstraint​(double 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

      • LessEqualConstraint

        public LessEqualConstraint​(int 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

      • test

        public void test​(java.lang.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 java.lang.String getDescription​(java.lang.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
