Data Fields
float *	values
	Array with values.
unsigned int	num_values
	Number of currently used values.
unsigned int	max_values
	Number of elements in the array.
uint8_t	storeidx
	Index of the store.

Detailed Description

Implementation of a store using in-memory float values.

A new floatstore must be initialized with a user provided array of float values using ua_floatstore_init(). The number of elements in the array is the capacity of the store. Then variables can be registered using ua_floatstore_register_node(), which connects the variable value attribute with one store element.

The raw float array is the data source of this store and can be directly accessed to set new float values.

Member Function Documentation

static ua_statuscode ua_floatstore_attach_value	(	void *	floatstore,
		ua_node_t	node,
		unsigned int	idx,
		struct ua_indexrange *	range,
		unsigned int	num_ranges,
		struct ua_datavalue *	value
	)

Implementation of the ua_store_attach function for the floatstore.

float * ua_floatstore_clear

(

struct ua_floatstore *

store

)

Clears the given store.

Parameters

store

Pointer to store context.

Returns

The values array passed in ua_floatstore_init.

static void ua_floatstore_get_value	(	void *	floatstore,
		ua_node_t	node,
		unsigned int	idx,
		bool	source_ts,
		struct ua_indexrange *	range,
		unsigned int	num_ranges,
		struct ua_datavalue *	result
	)

Implementation of the ua_store_get function for the floatstore.

int ua_floatstore_init	(	struct ua_floatstore *	store,
		uint8_t	storeidx,
		float *	values,
		unsigned int	num_values
	)

Initializes the float store.

Parameters

store	Pointer to store context.
storeidx	Requested store index. 0 = auto assign new index.
values	Array of float values.
num_values	Array size of values.

Returns

Zero on success or errorcode on failure.

int ua_floatstore_register_node	(	struct ua_floatstore *	store,
		float	initial_value,
		ua_node_t	node
	)

Registers the given node in the floatstore.

This allocated a new slot in the real store and assigns the correct value_index to the node.

Parameters

store	Context of the floatstore.
initial_value	Initial value for this variable.
node	Handle of node associated with the value.

Returns

Zero on success or errorcode on failure.
