Member Function Documentation

unsigned* ASCcontribution::cnoPtr

(

)

const [inline]

Returns:

- pointer to the start of the cno summary data

ASCcontribution * ASCcontribution::create	(	unsigned char *	buffer,
		unsigned	size,
		bool	swap = !DFC_BIG_ENDIAN
	)			[inline, static]

Create an ASCcontribtuion from a Python string.

This method is here to support the Python interface. A Python string is cast to an ASCcontribution. If this class had anything but a no-op constructor this would not work and we would have to use placement new. The reason this wasn't done right off the bat is that it isn't entirely clear that we know how to do this correctly vis a vis the Python object reference counting. Sometimes a Python crash is observed that complains about an object already being marked for garbage collection. I have not been able to narrow this down to a particular class, but think it might have to do with the placement new used in the LATdatagram class.

Parameters:

	buffer	- A buffer containing an ASCcontribution in string form
	size	- The size of the buffer
	swap	- Optional parameter to force or not force in place byte swapping

Returns:

- A pointer to the buffer cast as an ASCcontribution

unsigned char * ASCcontribution::string

(

bool

swap = !DFC_BIG_ENDIAN

)

[inline]

Return this ASCcontribution in string form.

Parameters:

swap

- Boolean to cause the buffer to be byte swapped in place

Returns:

A pointer to this ASCcontribution cast as an array of unsigned chars

Reimplemented from LATcontribution.
