Detailed Description

This class is the implementation of the AlarmDouble IDL interface defined in baci.idl. It is used so that we may create a local alarm for the value of a remote BACI property. There are only two useful methods: alarm_raised and alarm_cleared. They do just what their names imply.

Member Function Documentation

void MyAlarmdouble::alarm_cleared	(	CORBA::Double	value,
		const ACSErr::Completion &	c,
		const ACS::CBDescOut &	desc
	)

Method invoked when the double value goes back into the acceptable range.

Parameters:

	value	The double's new value
	c	Error handing structure.
	desc	Callback descriptor

Returns:

void

---

void MyAlarmdouble::alarm_raised	(	CORBA::Double	value,
		const ACSErr::Completion &	c,
		const ACS::CBDescOut &	desc
	)

Method invoked when the double value goes out of range.

Parameters:

	value	The double's current (i.e., out of range) value
	c	Error handing structure.
	desc	Callback descriptor

Returns:

void

---

CORBA::Boolean MyAlarmdouble::negotiate	(	ACS::TimeInterval	time_to_transmit,
		const ACS::CBDescOut &	desc
	)			[inline]

Method used so that client and servant can agree upon the time it takes to transmit data (generally invocations of the done method). A smart callback implementation would analize the value of time_to_transmit and decide whether the value is acceptable, but we just return true regardless in this simplistic example.

Parameters:

	time_to_transmit	Time to transmit data.
	desc	Callback descriptor

Returns:

True regardless of parameter values.
