Detailed Description

Extension of the DataManager interface which provides methods to register modified fields.

Member Function Documentation

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

pure virtual

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

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

pure 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

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

pure 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.

virtual uint32_t fesa::FieldDataManager::registerField ( AbstractField & field )

pure virtual

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

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

pure virtual

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