API Description

Lightweight base "class" for handling all BACnet objects belonging to a BACnet device, as well as Device-specific properties. This Device instance is designed to meet minimal functionality for simple clients.

Function Documentation

uint16_t Device_Vendor_Identifier

(

void

)

Returns the Vendor ID for this Device. See the assignments at http://www.bacnet.org/VendorID/BACnet%20Vendor%20IDs.htm

Returns

The Vendor ID of this Device.

unsigned Device_Object_List_Count

(

void

)

Get the total count of objects supported by this Device Object.

Note

Since many network clients depend on the object list for discovery, it must be consistent!

Returns

The count of objects, for all supported Object types.

Here is the caller graph for this function:

bool Device_Object_List_Identifier	(	unsigned	array_index,
		int *	object_type,
		uint32_t *	instance
	)

Lookup the Object at the given array index in the Device's Object List. Even though we don't keep a single linear array of objects in the Device, this method acts as though we do and works through a virtual, concatenated array of all of our object type arrays.

Parameters

array_index	[in] The desired array index (1 to N)
object_type	[out] The object's type, if found.
instance	[out] The object's instance number, if found.

Returns

True if found, else false.

Here is the caller graph for this function:

bool Device_Valid_Object_Name	(	BACNET_CHARACTER_STRING *	object_name1,
		int *	object_type,
		uint32_t *	object_instance
	)

Determine if we have an object with the given object_name. If the object_type and object_instance pointers are not null, and the lookup succeeds, they will be given the resulting values.

Parameters

object_name	[in] The desired Object Name to look for.
object_type	[out] The BACNET_OBJECT_TYPE of the matching Object.
object_instance	[out] The object instance number of the matching Object.

Returns

True on success or else False if not found.

Here is the call graph for this function:

bool Device_Valid_Object_Id	(	int	object_type,
		uint32_t	object_instance
	)

Determine if we have an object of this type and instance number.

Parameters

object_type	[in] The desired BACNET_OBJECT_TYPE
object_instance	[in] The object instance number to be looked up.

Returns

True if found, else False if no such Object in this device.

bool Device_Object_Name_Copy	(	BACNET_OBJECT_TYPE	object_type,
		uint32_t	object_instance,
		BACNET_CHARACTER_STRING *	object_name
	)

Copy a child object's object_name value, given its ID.

Parameters

object_type	[in] The BACNET_OBJECT_TYPE of the child Object.
object_instance	[in] The object instance number of the child Object.
object_name	[out] The Object Name found for this child Object.

Returns

True on success or else False if not found.
