cardinal ResourceUtilizationPoint::grahamScanResourceUtilizationList	(	ResourceUtilizationPoint *	rup,
		const cardinal	count
	)		`[static]`

Compute convex hull on resource/utilization list using Graham Scan algorithm.

Parameters:

rup	List.
count	Number of entries in list.

Returns:: Number of entries remaining in list.

cardinal ResourceUtilizationPoint::mergeResourceUtilizationLists	(	ResourceUtilizationPoint *	destination,
		ResourceUtilizationPoint **	listArray,

listArray	Array of lists to merge.
listSizeArray	Array of list sizes.
listCount	Number of lists.

Returns:: Number of points in destination list.

int ResourceUtilizationPoint::operator!= ( const ResourceUtilizationPoint & rup ) const [inline]

Operator "!=".

int ResourceUtilizationPoint::operator== ( const ResourceUtilizationPoint & rup ) const [inline]

Operator "==".

cardinal ResourceUtilizationPoint::optimizeResourceUtilizationList	(	ResourceUtilizationPoint *	rup,
		const cardinal	count
	)		`[static]`

Optimize resource/utilization list by utilization: Eliminate points which have higher resource requirements or cost than higher-utilized points following.

Parameters:

rup	List.
count	Number of entries in list.

Returns:: Number of entries remaining in list.

void ResourceUtilizationPoint::reset ( )

Reset.

void ResourceUtilizationPoint::sortResourceUtilizationList	(	ResourceUtilizationPoint *	rup,
		const integer	start,
		const integer	end
	)		`[static]`

Sort resource/utilization list by utilization.

Parameters:

rup	List.
start	First point number.
end	Last point number.
