Typedef Documentation

on_get_security_store_cb

typedef int(* on_get_security_store_cb) (SESSION_T *session, const SECURITY_STORE_T store, void *context)

Callback for get_security_store().

Parameters

session	The current active session.
response	The response containing the security store contents. This structure will be freed on exit so a copy should be taken if it needs to be used outside of the scope of the callback.
context	User-supplied context from the get_security_store() call.

Returns

HANDLER_SUCCESS or HANDLER_FAILURE.

on_update_security_store_cb

typedef int(* on_update_security_store_cb) (SESSION_T *session, const LIST_T *error_reports, void *context)

Callback for update_security_store().

Parameters

session	The current active session.
error_reports	Any errors that have occurred while processing the updated.
context	User-supplied context from the update_security_store() call.

Returns

HANDLER_SUCCESS or HANDLER_FAILURE.

Enumeration Type Documentation

GLOBAL_PERMISSIONS_T

enum GLOBAL_PERMISSIONS_T

Permissions that protect globally scoped, access-controlled operations.

Enumerator
GLOBAL_PERMISSION_AUTHENTICATE	Add an authentication handler.
GLOBAL_PERMISSION_VIEW_SESSION	List or listen to client sessions.
GLOBAL_PERMISSION_MODIFY_SESSION	Alter a client session. This covers a range of actions including: subscribe session to a topic enable conflation for a sessioh close session
GLOBAL_PERMISSION_REGISTER_HANDLER	Required to register any server side handler.
GLOBAL_PERMISSION_VIEW_SERVER	View the server's runtime state - for example, read JMX MBeans.
GLOBAL_PERMISSION_CONTROL_SERVER	Change the server's runtime state - for example, shut it down.
GLOBAL_PERMISSION_VIEW_SECURITY	Read the security configuration.
GLOBAL_PERMISSION_MODIFY_SECURITY	Change the security configuration.
GLOBAL_PERMISSION_UNKNOWN	A permission that is unsupported by the session.
GLOBAL_PERMISSION_READ_TOPIC_VIEWS	Read topic views.
GLOBAL_PERMISSION_MODIFY_TOPIC_VIEWS	Modify topic views.

PATH_PERMISSIONS_T

enum PATH_PERMISSIONS_T

Since

6.5 Permissions protecting access-controlled operations that are evaluated for a specific path.

Enumerator
PATH_PERMISSION_READ_TOPIC	Required to receive information from a topic. If a session does not have read_topic permission for a topic, the topic will be excluded from the results of subscription or fetch operations for the session, and the topic's details cannot be retrieved by the session.
PATH_PERMISSION_UPDATE_TOPIC	Update a topic.
PATH_PERMISSION_MODIFY_TOPIC	Add a topic or remove a topic.
PATH_PERMISSION_SEND_TO_MESSAGE_HANDLER	Send a message to a handler registered with the server.
PATH_PERMISSION_SEND_TO_SESSION	Send a message to a client session.
PATH_PERMISSION_SELECT_TOPIC	Use a topic selector that selects the topic path. A session must have this permission for the path prefix of any topic selector used to subscribe or fetch. When the subscription or fetch request completes, the resulting topics are further filtered based on the PATH_PERMISSION_READ_TOPIC permission. A session that has PATH_PERMISSION_READ_TOPIC but not PATH_PERMISSION_SELECT_TOPIC for a particular topic path cannot subscribe directly to topics belonging to the path. However, the session can be independently subscribed by a control session that has GLOBAL_PERMISSION_MODIFY_SESSION permission in addition to the appropriate PATH_PERMISSION_SELECT_TOPIC permission.
PATH_PERMISSION_ACQUIRE_LOCK	Acquire a session lock.
PATH_PERMISSION_UNKNOWN	A permission that is unsupported by the session.
