Function Documentation

register_callback_by_type()

void attribute_store::register_callback_by_type	(	node_changed_callback	callback_function,
		attribute_store_type_t	type
	)

Register a callback function to any node with a given type.

Note

We can't check uniqueness of the callback function, so it's up to the user to make sure that the same callback function is not registered multiple times.

Parameters

callback_function	The function to invoke when the node's value is updated.
type	The attribute node type for which a callback will be registered.

register_callback_by_type_and_state()

void attribute_store::register_callback_by_type_and_state	(	node_changed_callback	callback_function,
		attribute_store_type_t	type,
		attribute_store_node_value_state_t	value_state
	)

Register a callback function to any node with a given type and value state.

Note

We can't check uniqueness of the callback function, so it's up to the user to make sure that the same callback function is not registered multiple times.

Parameters

callback_function	The function to invoke when the node's value is updated.
type	The attribute node type for which a callback will be registered.
value_state	The value state for which a callback will be registered.
