Member Function Documentation

void Jpetra::MultiVector::copyAndPermute	(	DistObject	distObjectSource,
		int	numSameGids,
		int[]	permuteToLids,
		int[]	permuteFromLids,
		int	combineMode
	)		[inline, virtual]

Should not be called directly by the user.

This method must be overridden by classes extending DistObject.

Parameters:

distObjectSource	The object from which local values will be copied and permuted.
numSameGids	The number of global ids that are the same starting from myMinGlobalEntryId.
permuteToLids	The local IDs of this DistObject that will permute elements from distObjectSource according to the corresponding local IDs in permuteFromLids.
permuteFromLids	The local IDs from distObjectSource that will be permuted to the local IDs in permuteToLids correspndong to this DistObject.
combineMode	One of the declared combine mode constants in DistObject.

Implements Jpetra::DistObject.

Serializable [] Jpetra::MultiVector::packAndPrepare	(	DistObject	distObjectSource,
		int[]	exportGids,
		int[]	exportLids
	)		[inline, virtual]

Should not be called directly by the user.

This method must be overridden by classes extending DistObject.

Parameters:

distObjectSource	The object from which elements will be packedup for exportation to other vnodes.
exportGids	The global IDs of the elements to be exported.
exportLids	The local IDs of elements to be exported.

Returns:

The packed data that Distributor.distribute will export to other vnodes.

Implements Jpetra::DistObject.

int [][] Jpetra::MultiVector::unpackAndCombine	(	Serializable[]	importData,
		int	combineMode
	)		[inline, virtual]

Should not be called directly by the user.

This method must be overridden by classes extending DistObject.

Parameters:

importData	The data object returned from Distributor.distribute which contains all elements sent to this vnode.
combineMode	One of the declared combine mode constants in DistObject.

Implements Jpetra::DistObject.
