Detailed Description

Implementation of FieldDataManager for shared setting fields.

Member Function Documentation

const void * fesa::FieldTrackerDataManager::getFieldAddress	(	uint16_t	bufferIndex,
		uint32_t	fieldIndex
	)

virtual

Returns the address of the field whose index id fieldIndex in the reader buffer whose index is bufferIndex.

std::size_t fesa::FieldTrackerDataManager::getSharedFieldsSize	(	std::size_t	numberOfFieldSlots,
		bool	multiProcess
	)		const

virtual

Returns the size of the fields shared between the server and RT parts.

Parameters

numberOfFieldSlots	total number of field slots to reserve memory for.
multiProcess	true if multiple process will access the shared fields, false otherwise

void fesa::FieldTrackerDataManager::initialCopy ( )

virtual

Performs the initial copy of the data from the reference buffer to the reader buffers. Called once before any call to update().

void fesa::FieldTrackerDataManager::mapSharedFields	(	char *	memory,
		std::size_t	numberOfFieldSlots,
		bool	multiProcess,
		bool	first
	)

virtual

Maps the shared fields, starting at the address pointed to by memory.

Parameters

memory	address where the mapping starts
numberOfFieldSlots	number of field slots for which memory was reserved
multiProcess	true if multiple process will access the shared fields, false otherwise
first	true if shared fields must be initialized (typically when fields are mapped for the first time), false otherwise.

uint32_t fesa::FieldTrackerDataManager::registerField ( AbstractField & field )

virtual

Registers a field as synchronizable (normally only shared setting fields).

uint32_t fesa::FieldTrackerDataManager::registerModifiedFields ( const std::set< ModifiedField > & fields )

virtual

Registers a field as modified. To be called after field slots have been modified, so that they will be synchronized.

void fesa::FieldTrackerDataManager::update	(	uint16_t	oldIndex,
		uint16_t	newIndex
	)

virtual

Updates the reader buffers. Called by BufferSynchronizer when an update can be safely done.

Parameters

oldIndex	index of the reader buffer which is about to become the old buffer
newIndex	index of the reader buffer which is about to become the new buffer
