enum	MuxContextType
	Category of multiplexing context.

enum	ActionType
	Action where the context is going to be use.

	Definition of the different modes of field access.

Public Member Functions
virtual	~MultiplexingContext ()
	Destructor.

timestamp_ns	getCycleStamp () const
	Returns the time of the start-cycle event which occurs at the start of the first basic period of the given cycle. It is expressed as a 64-bit integer counting the number of nanoseconds elapsed since the UNIX epoch i.e. since January 1st 1970 at 00.00 A.M. The constant UNKNOWN_TIMESTAMP is return if the cycle stamp is unknown.

timestamp_ns	getTimeStamp () const
	returns the timeStamp associated to the context More...

int32_t	getCycleId () const
	returns the cycle ID More...

const std::string &	getTimingDomainName () const

const std::string &	getCycleName () const
	returns the cycle name as string More...

virtual void	serialize (std::ostream &stream)
	this method serializes the multiplexing context into the stream

const std::string &	getExtraCondition () const
	returns the extra condition More...

void	setExtraCondition (const std::string &extraCondition)
	Sets the extra condition. More...

bool	match (const std::string &cycleSelector) const
	Matches the context with a cycle-string argument, in order to check if the context lies within this argument. The match function is implemented by the different childs of this class. More...

Protected Attributes
std::string	cycleName_
	contains the name of the cycle

std::string	extraCondition_
	This condition can be used for advanced multiplexing.

timestamp_ns	timeStamp_
	contains the time stamp of the event.

timestamp_ns	cycleStamp_
	contains the time stamp of start of the cycle in which the event occurred or UNKNOWN_TIMESTAMP.

MuxContextType	type_
	Indicates the type of multiplexing context This information is used for the Data Integrity Later.

ActionType	actionType_
	Indicates which type of action is going to use the context.

bool	forewarning_
	Indicates that the context belongs to the next cycle, not to the current one. For example to control a slow power converter where you need to send the settings one cycle in advance, to give time to the power converter to follow the new request.

std::string	timingDomainName_
	timing domain name

uint8_t	settingAccessMask_
	setting access mask

uint8_t	acquisitionAccessMask_
	acquisition access mask
