General addressspace management like register/unregister namespaces.
int ua_addressspace_foreach_node | ( | uint16_t | nsidx, |
int(*)(ua_node_t handle) | callback | ||
) |
Iterates over all nodes in namespace and calls the given callback.
This functions uses the internal hashtable to iterate efficiently over all nodes without the need of following UA references.
nsidx | Namespace to iterate through. |
callback | Callback to call for each node. This callback will receive the node handle, so you can perform any task on the node. A typical usage of callback is to use simply ua_node_remove as callback, which will remove all nodes of the give namespace. |
uint16_t ua_addressspace_get_nsidx | ( | struct ua_addressspace * | addr | ) |
Returns the namespace index for the given address space.
addr | Address space context. |
const char* ua_addressspace_get_nsuri | ( | struct ua_addressspace * | addr | ) |
Returns the namespace URI for the given address space.
addr | Address space context. |
struct ua_addressspace* ua_addressspace_getaddr | ( | uint16_t | nsidx | ) |
Get the pointer to the ua_addressspace struct of a namespace.
nsidx | Index of the namespace. |
int ua_addressspace_init | ( | void | ) |
Allocate resources for addressspace management.
bool ua_addressspace_is_static | ( | struct ua_addressspace * | addr | ) |
Returns true if the address space is static.
Static means it's compiled into the application and is constant. On embedded systems static address space can lie in ROM.
struct ua_addressspace* ua_addressspace_lookup_uri | ( | const char * | nsuri | ) |
Finds address space context by is URI.
nsuri | Namespace URI of the namespace. |
void ua_addressspace_print_stat | ( | uint16_t | nsidx | ) |
Print addressspace statistics for a namespace.
The statistics are printed to trace at level debug and facility session.
nsidx | index of namespace to print statistics for |
int ua_addressspace_register | ( | const char * | url, |
struct ua_addressspace_config * | config, | ||
enum ua_addressspace_index_type | type | ||
) |
Registers a new namespace.
url | URL of namespace. |
config | Address space configuration which defines the pool sizes. |
type | Index type to use for indexing nodes. Note: Using UA_INDEX_HASHTABLEQP is not allowed as deleting nodes would corrupt the hashtable. |

int | hashtablesize, | ||

nsidx | Requested namespace index. Set to -1 if you don't care. |
num_placeholders | Number of placeholde references that get allocated in RAM. |
type | Index type to use for indexing nodes. |
void ua_addressspace_set_digest | ( | const unsigned char * | digest, |
size_t | len | ||
) |
Set the digest which was used to generate NS0.

size_t | len | ||
) |
Returns true if the digest is ok, false otherwise.
