The create class method is used to create new dynamically allocated instances of this class.
- Parameters
-
deeper | The incoming data source to be filtered |
address | The address to place the checksum. |
length | The number of bytes of checksum to be placed into the result. |
end | The byte order. |
width | The width of the values being summed. Usually 1 byte, but wider combinations are possible. If you use something wider, it is assumed that they are alligned on multiples of that width, no provision for an offset is provided. |
