Detailed Description

TimeService Object Implementation.

The Object implementation implements methods to retrieve GLOBAL time as well as secure GLOBAL time. The times are retrieved as UTOs. The object also allows creation of a TIO for a given time interval. In general, the TimeService clerk manages the UTOs and the TIOs. The notion of time returned here is the globally synchronized time.

	)

Constructor.

TAO_Time_Service_Clerk::~TAO_Time_Service_Clerk ( void )

Destructor.

Member Function Documentation

CORBA::ULongLong TAO_Time_Service_Clerk::get_time ( void )

virtual

Return the globally synchronized time.

TimeBase::InaccuracyT TAO_Time_Service_Clerk::inaccuracy ( void )

Get method for inaccuracy.

void TAO_Time_Service_Clerk::inaccuracy ( TimeBase::InaccuracyT inaccuracy )

Set method for inaccuracy.

CosTime::TIO_ptr TAO_Time_Service_Clerk::new_interval	(	TimeBase::TimeT	lower,
		TimeBase::TimeT	upper
	)

virtual

This creates a new TIO with the given parameters.

CosTime::UTO_ptr TAO_Time_Service_Clerk::new_universal_time	(	TimeBase::TimeT	time,
		TimeBase::InaccuracyT	inaccuracy,
		TimeBase::TdfT	tdf
	)

virtual

This creates a new UTO based on the given parameters.

CosTime::UTO_ptr TAO_Time_Service_Clerk::secure_universal_time ( void )

virtual

This operation returns the global time in a UTO only if the time can be guaranteed to have been obtained securely. Currently this operation is not implemented and throws a CORBA::NO_IMPLEMENT exception, if called.

CORBA::Short TAO_Time_Service_Clerk::time_displacement_factor ( void )

Returns the time displacement factor.

void TAO_Time_Service_Clerk::time_displacement_factor ( CORBA::Short tdf )

Set the TDF.

CosTime::UTO_ptr TAO_Time_Service_Clerk::universal_time ( void )

virtual

This operation returns the global time and an estimate of inaccuracy in a UTO.

CosTime::UTO_ptr TAO_Time_Service_Clerk::uto_from_utc ( const TimeBase::UtcT & utc )

virtual

This creates a new UTO given a time in the UtcT form.

Helper class to help in the updation of time.

Member Data Documentation

Timer_Helper TAO_Time_Service_Clerk::helper_

private

This is a friend class that inherits from the Event Handler class. The handle_timeout method of this class is scheduled for periodic invocation by the reactor. This method, in turn, updates the clerks notion of time. Using this class obviates the need for the clerk to multiple inherit from the servant base as well as the event handler.

TimeBase::InaccuracyT TAO_Time_Service_Clerk::inaccuracy_

private

Inaccuracy in the time.

IORS TAO_Time_Service_Clerk::server_

private

Set of server Time Server IORs.

CORBA::ULongLong TAO_Time_Service_Clerk::time_

Clerk's notion of time.

CORBA::Short TAO_Time_Service_Clerk::time_displacement_factor_

private

Time displacement factor in minutes.

CORBA::ULongLong TAO_Time_Service_Clerk::update_timestamp_

private

Time when last global synchronization was done.
