#include <ScalarField.h>

Inheritance diagram for FieldData:

Classes
struct	PrivateTag
	Used to prevent direct use of ScalarField constructors, and force the shared_ptr usage. More...

Public Types
typedef void	DataType
	this base class has no specific data type

Public Member Functions
void	absorbScale () const
	absorb scale factor into data

void	zero ()
	initialize to zero

void *	data (bool shouldAbsorbScale=true)
	get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified)

const void *	data (bool shouldAbsorbScale=true) const
	get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified)

void *	dataGpu (bool shouldAbsorbScale=true)
	get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified)

const void *	dataGpu (bool shouldAbsorbScale=true) const
	get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified)

DECLARE_DATA_PREF_ACCESS bool	isOnGpu () const
	Check where the data is (for #ifdef simplicity exposed even when no GPU_ENABLED)

	FieldData (const GridInfo &gInfo, string category, int nElem, int nDoublesPerElem=1, bool onGpu=false)

void	copyData (const FieldData &other)
	copy data and scale (used by clone())

void	send (int dest, int tag=0) const
	send to another process

void	recv (int src, int tag=0)
	receive from another process

void	bcast (int root=0)
	synchronize across processes (using value on specified root process)

void	allReduce (MPIUtil::ReduceOp op, bool safeMode=false)
	apply all-to-all reduction

Public Attributes
int	nElem
	number of elements = #gInfo.nr

double	scale
	overall scale factor of the data array

const GridInfo &	gInfo
	simulation grid info
