static void	copy (size_t pDest, const size_t pSource, size_t nDims)
	This just wraps memcpy. More...

static void	deserialize (size_t *pVec, GDomListIterator &it)

static void GClasses::GIndexVec::copy	(	size_t *	pDest,
		const size_t *	pSource,

static

This just wraps memcpy.

static void GClasses::GIndexVec::deserialize	(	size_t *	pVec,

	)

static

Load the vector from a text format. pVec must be large enough to contain all of the elements that remain in "it".

void GClasses::GIndexVec::fillIndexes ( )

Fills this vector with the values 0, 1, 2, ...

static size_t GClasses::GIndexVec::indexOfMax	(	size_t *	pVec,

	)

static

Returns the index of the max value. In the event of a tie, the smallest index of one of the max values is returned.

static void GClasses::GIndexVec::makeIndexVec	(	size_t *	pVec,

	)

static

Makes a vector of ints where each element contains its index (starting with zero, of course)
