Member Function Documentation

int32_t fesa::RollingBufferMuxManager::getClosestSlot ( timestamp_ns timestamp )

virtual

Returns the slot closest to the given timestamp.

Parameters

timestamp the timestamp to look for

Reimplemented from fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getClosestSlot	(	const std::string &	cycleName,
		timestamp_ns	timestamp
	)

virtual

Returns the slot closest to the given timestamp whose cycle matches cycleName.

Parameters

cycleName	the name of the cycle to look for
timestamp	the timestamp to look for

Reimplemented from fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getDepth ( )

inlinevirtual

This method returns the depth of the multiplexing manager.

Returns: the depth of the multiplexing manager

Reimplemented from fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getLastSlot ( const std::string & cycleName )

protectedvirtual

This method returns the slot in which the last value for the virtual accelerator passed by argument was stored.

Parameters

cycleId the ID of the cycle for the requested slot

Returns: the last slot used by the requested cycle

Implements fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getLastSlot ( int32_t cycleId )

protectedvirtual

This method returns the slot in which the last value for the virtual accelerator passed by argument was stored.

Parameters

cycleId the ID of the cycle for the requested slot

Returns: the last slot used by the requested cycle

Implements fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getSlotByCycleName ( const std::string & cycleName )

virtual

This method the last given cycleName set slot.

Returns: The last cyclename slot.

Reimplemented from fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::getSlotByTimeStamp ( int64_t timeStamp )

virtual

Returns the slot corresponding to timeStamp, or INVALID_SLOT if this feature is not supported by the concrete MultiplexingManager.

Exceptions

FesaException if no slot is assigned timeStamp.

Reimplemented from fesa::AbstractMultiplexingManager.

void fesa::RollingBufferMuxManager::mapMemory	(	char *&	address,
		bool	first,
		std::ostream &	logStream
	)

virtual

Maps shared fields to the memory pointed to by address.

Parameters

[in,out]	address	address where to map shared fields. It is updated to point to the byte following the last byte mapped.
	first	true if this is the first process to map the shared fields
	logStream	stream on which details of the mapping are output

Reimplemented from fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::requireSlot ( const MultiplexingContext & context )

virtual

This method returns the next slot in which the value of a field will be stored.

Parameters

context the multiplexing context for which a slot is requested

Returns: the slot where the data can be stored

Implements fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::requireSlot ( const std::string & cycleName )

protectedvirtual

This method returns the next slot in which the value of a field will be stored.

Parameters

cycleId the ID of the cycle for the requested slot

Returns: the slot where data can be stored

Implements fesa::AbstractMultiplexingManager.

int32_t fesa::RollingBufferMuxManager::requireSlot ( int32_t cycleId )

protectedvirtual

This method returns the next slot in which the value of a field will be stored.

Parameters

cycleId the ID of the cycle for the requested slot

Returns: the slot where data can be stored

Implements fesa::AbstractMultiplexingManager.
