class kanzi::connect::PolicyContextInterface : public MetaObject

Policy context interface.

Public Functions

~PolicyContextInterface()

Destructor.

bool acceptClientConnection(ConnectedClientSharedPtr client) = 0

Determines whether policy allows client connection to be accepted.

Return

true if connection is to be accepted.

Parameters

  • client: contains information about connected client

bool acceptPluginLoading(const string &plugin) = 0

Invoked to check whether loading of a plugin is allowed.

Return

true if plugin loading should be allowed. false if not. Plugin loading might be disallowed for example because plugin signature mismatch.

Parameters

  • plugin: the plugin that is to be loaded. This might be relative or absolute path to the plugin

void addClient(ConnectedClientSharedPtr client) = 0

Adds a client reference into a collection of clients.

ToDo: Consolidate with accept, no need for two methods !!

Parameters

  • client: the client identifiers.

PolicyControllerInterfaceSharedPtr getController() = 0

Retrieve policy controller instance.

Return

policy controller instance.

void initialize(ConnectDomainSharedPtr domain) = 0

Optional two phased constructor (used when domain is not available construction time)

Parameters

  • domain: connect domain.

bool registerClientMeasurements(DiagnosticsManagerSharedPtr diagnostics, ConnectedClientSharedPtr connectedClient) = 0

Register diagnostics values for service identified by connectedclient to be available for policies.

Return

true on success

Parameters

  • diagnostics: Pointer to the diagnostics mechanism.

  • connectedClient: Pointer to the connecting client.

void registerConnection(const string &interfaceId, ConnectedClientSharedPtr connectedClient) = 0

Register mapping between client and service.

Parameters

  • interfaceId: The name of the service to which to connect.

  • connectedClient: Pointer to the connecting client.

void registerDataToPolicy(string serviceName) = 0
void registerDataToPolicy(AbstractServiceSharedPtr service) = 0
void registerServerQueueRTSAccessors(WorkItemDispatcher *queue) = 0

Create the policy RTS accessors for message queues.

bool registerServiceMeasurements(DiagnosticsManagerSharedPtr diagnostics, const string &interfaceid) = 0

Register diagnostics values for service named interfaceid to be available for policies.

Return

true on success

Parameters

  • diagnostics: Pointer to the diagnostics mechanism.

  • interfaceid: The name of the interface, corresponds to service name.

void removeClient(int clientId) = 0

Removes a client with specific client identifier.

ToDo: Should be symmetrical to adding new clients (i.e. shared ptr instead of token)

Parameters

  • clientId: the client identifier to remove.
