public IntegralType(String name, Class clazz, int enumType)

        super(name, clazz, enumType);
Methods Summary
public java.lang.NumbergetValue(java.lang.Number value)
Converts the specified value into a value of this numeric type. E.g. an Integer is converted into a Long, if this represents the numeric type long.

param
value value to be converted
return
converted value

        Number ret = null;

        if (value == null)
            ret = null;
        else if ("int".equals(getName()))
            ret = new Integer(value.intValue());
        else if ("long".equals(getName()))
            ret = new Long(value.longValue());
        else if ("byte".equals(getName()))
            ret = new Byte(value.byteValue());
        else if ("short".equals(getName()))
            ret = new Short(value.shortValue());

        return ret;
public java.lang.Numbernegate(java.lang.Number value)
Returns -value.

param
value value to be negated
return
-value

        Number ret = null;

        if (value == null)
            ret = null;

            ret = new Integer(-value.intValue());
        else if ("long".equals(getName()))
            ret = new Long(-value.longValue());
        else if ("byte".equals(getName()))
            ret = new Byte((byte)-value.byteValue());
        else if ("short".equals(getName()))
            ret = new Short((short)-value.shortValue());

        return ret;
