Member Function Documentation

bool Tango::Attribute::check_alarm

(

)

Check if the attribute read value is below/above the alarm level.

Returns:

A boolean set to true if the attribute is in alarm condition.

Exceptions:

DevFailed

If no alarm level is defined. Click here to read DevFailed exception specification

void Tango::Attribute::fire_archive_event

(

DevFailed *

except = NULL

)

Fire an archive event for the attribute value.

The event is pushed to the notification daemon. The attibute data must be set with one of the Attribute::set_value or Attribute::setvalue_date_quality methods before fireing the event. The event is triggered with or without the archive event criteria depending on the configuration choosen with set_archive_event(). ATTENTION: The couple set_value() and fire_archive_event() needs to be protected against concurrent accesses to the same attribute. Such an access might happen during a synchronous read or by a reading from the polling thread. Inside all methods reading or writing commands and attributes this protection is automatically done by the Tango serialisation monitor. When fireing archive events in your own code, you should use the push_archive_event methods of the DeviceImpl class or protect your code with the Tango::AutoTangoMonitor on your device. Example:

{ Tango::AutoTangoMonitor synch(this); att_temp_seq.set_value (temp_seq, 100); att_temp_seq.fire_archive_event (); }

Parameters:

except

A pointer to a DevFailed exception to be thrown as archive event.

void Tango::Attribute::fire_change_event

(

DevFailed *

except = NULL

)

Fire a change event for the attribute value.

The event is pushed to the notification daemon. The attibute data must be set with one of the Attribute::set_value or Attribute::setvalue_date_quality methods before fireing the event. The event is triggered with or without the change event criteria depending on the configuration choosen with set_change_event(). ATTENTION: The couple set_value() and fire_change_event() needs to be protected against concurrent accesses to the same attribute. Such an access might happen during a synchronous read or by a reading from the polling thread.

{ Tango::AutoTangoMonitor synch(this); att_temp_seq.set_value (temp_seq, 100); att_temp_seq.fire_archive_event (); }

Parameters:

except

A pointer to a DevFailed exception to be thrown as archive event.

void Tango::Attribute::fire_event	(	vector< string > &	filt_names,
		vector< double > &	filt_vals,
		DevFailed *	except = NULL
	)

Fire a user event for the attribute value.

The event is pushed to the notification daemon. The attibute data must be set with one of the Attribute::set_value or Attribute::setvalue_date_quality methods before fireing the event. ATTENTION: The couple set_value() and fire_event() needs to be protected against concurrent accesses to the same attribute.

This method stores the attribute read value, the date and the attribute quality factor inside the object. This data will be returned to the caller.

Please note that for Win32 user, the same method is defined using a "_timeb" structure instead of a "timeval" structure to set date.

Parameters:

	p_data	The attribute read value
	t	The date
	qual	The attribute quality factor
	x	The attribute x length. Default value is 1
	y	The attribute y length. Default value is 0
	release	The release flag. If true, memory pointed to by p_data will be freed after being send to the client. Default value is false.
