      • BinaryAsBigIntegerField

        public BinaryAsBigIntegerField(int offset,
                               int length,
                               boolean signed)
        Construct an instance.

        Parameters:
        offset - int the offset of this field
        length - int the size of the field in bytes
        signed - boolean true if the value is signed, false if unsigned

      • BinaryAsBigIntegerField

        public BinaryAsBigIntegerField(int offset,
                               int length,
                               int scale,
                               boolean signed)
        Construct an instance.

        Parameters:
        offset - int the offset of this field
        length - int the size of the field in bytes
        scale - a number <=0 implying a scaling factor to be muliplied by the stored byte value. For example, -1, would mean that the external value was 10 times the internal value.
        signed - boolean true if the value is signed, false if unsigned
