Detailed Description

An interface for handling observation callbacks from different objects.

Member Function Documentation

virtual bool M2MObservationHandler::observation_to_be_sent	(	M2MBase *	object,
		uint16_t	obs_number,
		const m2m::Vector< uint16_t > &	changed_instance_ids,
		bool	send_object = `false`
	)

pure virtual

The observation callback to be sent to the server due to a change in a parameter under observation.

Parameters

object	The observed object whose information needs to be sent.
obs_number	The observation number.
changed_instance_ids	A list of changed object instance IDs.
send_object	Indicates whether the whole object will be sent or not.

Returns: True if the message was send, False if there is already ongoing notification.

virtual void M2MObservationHandler::remove_object ( M2MBase * object )

pure virtual

A callback for removing an object from the list.

Parameters

object The M2MObject to be removed.

virtual void M2MObservationHandler::resource_to_be_deleted ( M2MBase * base )

pure virtual

A callback for removing an NSDL resource from the data structures.

Parameters

The	M2MBase derived observed object whose information needs to be removed.

virtual void M2MObservationHandler::send_delayed_response	(	M2MBase *	base,
		sn_coap_msg_code_e	code = `COAP_MSG_CODE_RESPONSE_CHANGED`
	)

pure virtual

Sends a delayed post response to the server with 'COAP_MSG_CODE_RESPONSE_CHANGED' response code.

Parameters

base	The resource sending the response.
code	Response code to be sent.

virtual void M2MObservationHandler::value_updated ( M2MBase * base )

pure virtual

A callback indicating that the value of the resource object is updated by server.

Parameters

base	The object whose value is updated.
object_name	The name of the updated resource, default is empty.
