Constructor & Destructor Documentation

◆ ~memory_walker_fletcher16()

virtual srecord::memory_walker_fletcher16::~memory_walker_fletcher16 ( )

virtual

The destructor.

Member Function Documentation

◆ create()

static pointer srecord::memory_walker_fletcher16::create	(	int	sum1,
		int	sum2,
		int	answer,
		endian_t	end
	)

static

The create class method is used to create new dynamically allocated instances of this class.

Parameters

sum1	The seed value for sum1. Defaults to zero.
sum2	The seed value for sum2. Defaults to zero.
answer	Set this to -1 to be completely ignored. If >= 0, this is the desired outcome if the checksum includes the checksum itself. The checksum returned will be calculated to return this desired outcome, when traversed, rather than a pure Fletcher-16 checksum.
end	The endian-ness of the checksum. This is needed to manipulate the answer. Ignored if answer is ignored.

◆ get()

unsigned srecord::memory_walker_fletcher16::get ( void ) const

The get method is used to get the Fletcher-16 checksum once all memory chunks have been processed by calls to our observe method.

◆ observe()

void srecord::memory_walker_fletcher16::observe	(	unsigned long	address,
		const void *	data,
		int	data_size
	)

protectedvirtual

The observe method is used by the memory walker to provide data.

Derived classes are required to impliment this method, and do something with the data.

Parameters

address	The base address of this chunk of memory.
data	The base address of this chunk of memory in memory.
data_size	The size, in bytes, of this chunk of memory.

Implements srecord::memory_walker.
