Detailed Description

The srecord::input_filter_checksum_bitnot class is used to represent the state of a checksum filter that inserts a bitnot sum into the data.

Definition at line 31 of file bitnot.h.

Constructor & Destructor Documentation

◆ ~input_filter_checksum_bitnot()

virtual srecord::input_filter_checksum_bitnot::~input_filter_checksum_bitnot ( )

virtual

The destructor.

Member Function Documentation

◆ create()

static pointer srecord::input_filter_checksum_bitnot::create	(	const input::pointer &	deeper,
		int	address,
		int	length,
		endian_t	end,
		int	width = `1`
	)

static

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.

◆ calculate()

sum_t srecord::input_filter_checksum_bitnot::calculate ( )

protectedvirtual

The calculate method is used to calculate the checksum to be written into the output, based on the "sum" instance variable.

Implements srecord::input_filter_checksum.
