attachForeignStorage()

void BatchHelpers::BatchData::attachForeignStorage

(

const std::vector< double > &

vec

)

Attach a foreign storage. Batches coming from this storage will be read only.

Definition at line 94 of file BatchData.cxx.

clear()

void BatchHelpers::BatchData::clear ( )

inline

Discard all storage.

getBatch()

RooSpan< const double > BatchHelpers::BatchData::getBatch	(	std::size_t	begin,
		std::size_t	batchSize
	)		const

Definition at line 25 of file BatchData.cxx.

makeWritableBatchInit()

RooSpan< double > BatchHelpers::BatchData::makeWritableBatchInit	(	std::size_t	begin,
		std::size_t	batchSize,
		double	value
	)

Make a batch and return a span pointing to the pdf-local memory.

Calls makeWritableBatchUnInit() and initialises the memory.

Parameters

[in]	begin	Begin of the batch.
[in]	batchSize	End of the batch (not included)
[in]	value	Value to initialise with (defaults to 0.).

Returns

An initialised RooSpan starting at event begin.

Definition at line 83 of file BatchData.cxx.

makeWritableBatchUnInit()

RooSpan< double > BatchHelpers::BatchData::makeWritableBatchUnInit	(	std::size_t	begin,
		std::size_t	batchSize
	)

Make a batch and return a span pointing to the pdf-local memory.

The batch status is switched to kWriting, but the batch is not initialised. If a batch at this start point exists, the storage will be resized to fit the required size.

Parameters

[in]	begin	Begin of the batch.
[in]	batchSize	Size of the batch.

Returns

An uninitialised RooSpan starting at event begin.

Definition at line 58 of file BatchData.cxx.

markDirty()

void BatchHelpers::BatchData::markDirty ( )

inline

Mark all batches dirty. This will trigger recomputations.

Definition at line 97 of file BatchData.h.

print()

void BatchHelpers::BatchData::print	(	std::ostream &	os,
		const std::string &	indent
	)		const

Print to given output stream.

Definition at line 103 of file BatchData.cxx.

setStatus()

bool BatchHelpers::BatchData::setStatus ( std::size_t  begin, std::size_t  size, Status_t  stat  )

inline

Set the status of a batch with the given start point and size.

The status of foreign read-only data will never change.

Returns

True if status successfully set, false if no such batch / not writable.

Definition at line 84 of file BatchData.h.

status()

Status_t BatchHelpers::BatchData::status ( std::size_t  begin, std::size_t  size  ) const

inline

Return the status of the batch starting at begin.

Parameters

[in]	begin	Start of the batch.
[in]	size	Size of the batch. This is used to check if the size of an existing batch matches the requested size. Asking for a too large size will be signalled by kNoBatch.

Definition at line 48 of file BatchData.h.

validRange()

bool BatchHelpers::BatchData::validRange ( std::size_t  begin, std::size_t  size  ) const
