Serializable Jpetra::CcjSupport::CcjGatherSerializableArray::elementAt	(	int	index,
		int	groupSize
	)		[inline]

Used internally by CCJ.

Parameters:

index	process ID or rank
groupSize	number of processes in the group

Returns:

ArrayList from process with this index

Serializable [] Jpetra::CcjSupport::CcjGatherSerializableArray::getAllElements
