enum mi::neuraylib::INeuray::Status

The operational status of the library.

Enumerator
PRE_STARTING	The library or the cluster has not yet been started.
STARTING	The library or the cluster is starting.
STARTED	The library or the cluster is ready for operation.
SHUTTINGDOWN	The library or the cluster is shutting down.
SHUTDOWN	The library or the cluster has been shut down.
FAILURE	There was a failure during operation.

Member Function Documentation

^◆ get_api_component() [1/2]

template<class T>

T * mi::neuraylib::INeuray::get_api_component ( ) const

inline

Returns an API component from the MDL SDK API.

This template variant requires that the API component is registered under the interface ID of the corresponding interface (which is the case for built-in API components).

See also: API components for a list of built-in API components.; register_api_component(), unregister_api_component()

Template Parameters

T	The type of the API components to be queried.

Returns: A pointer to the API component or NULL if the API component is not supported or currently not available.

^◆ get_api_component() [2/2]

virtual base::IInterface * mi::neuraylib::INeuray::get_api_component ( const base::Uuid & uuid ) const

pure virtual

Returns an API component from the MDL SDK API.

See also: API components for a list of built-in API components.; register_api_component(), unregister_api_component()

Parameters

uuid	The UUID under which the API components was registered. For built-in API components this is the interface ID of the corresponding interface.

Returns: A pointer to the API component or NULL if the API component is not supported or currently not available.

^◆ get_interface_version()

virtual Uint32 mi::neuraylib::INeuray::get_interface_version ( ) const

pure virtual

Returns the interface version of the MDL SDK library.

This number changes whenever the abstract interfaces of the MDL SDK API changes.

^◆ get_status()

virtual Status mi::neuraylib::INeuray::get_status ( ) const

pure virtual

Returns the status of the library.

Returns: The status

^◆ get_version()

virtual const char * mi::neuraylib::INeuray::get_version ( ) const

pure virtual

Returns the version of the MDL SDK library.

This string contains the product version, build number, build date, and platform of the current library.

^◆ register_api_component() [1/2]

virtual Sint32 mi::neuraylib::INeuray::register_api_component	(	const base::Uuid &	uuid,
		base::IInterface *	api_component
	)

pure virtual

Registers an API component with the MDL SDK API.

API components are a way for plugins to provide access to their functionality. The registration makes the API component available for subsequent calls of get_api_component().

Parameters

uuid	The ID of the API component to register, e.g., the interface ID of the corresponding interface.
api_component	The API component to register.

Returns

0: Success.
-1: Invalid parameters (NULL pointer).
-2: There is already an API component registered under the ID uuid.

^◆ register_api_component() [2/2]

template<class T>

Sint32 mi::neuraylib::INeuray::register_api_component ( T * api_component )

inline

Registers an API component with the MDL SDK API.

API components are a way for plugins to provide access to their functionality. The registration makes the API component available for subsequent calls of get_api_component().

This template variant registers the API component under the interface ID of the corresponding interface.

Parameters

api_component The API component to register.

Returns

0: Success.
-1: Invalid parameters (NULL pointer).
-2: There is already an API component registered under the ID T::IID().

^◆ shutdown()

virtual Sint32 mi::neuraylib::INeuray::shutdown ( bool blocking = true )

pure virtual

Shuts down the library.

For proper shutdown this may only be called after all transactions have been committed and all rendering is finished.

You also need to release all interface pointers related to functionality obtained after startup before calling this method. In case you use the mi::base::Handle class (or another handle class), you need to make sure that all such handles have been reset or destroyed.

Parameters

blocking Unused. The shutdown is always done in blocking mode.

Returns: 0, in case of success, -1 in case of failure

^◆ start()

virtual Sint32 mi::neuraylib::INeuray::start ( bool blocking = true )

pure virtual

Starts the operation of the MDL SDK library.

All configuration which is marked to be done before the start of the library must be done before calling this function. When calling this function the MDL SDK will start threads and start network operations etc. The MDL SDK library may not be ready for operation after the call returned if blocking mode is not used.

Parameters

blocking Unused. The startup is always done in blocking mode.

Returns

0: Success
-1: Unspecified failure.
-2: Authentication failure (challenge-response).
-4: Provided license expired.
-5: No professional GPU as required by the license in use was found. (historical - -6: Authentication failure (FLEXlm).)
-7: No NVIDIA VCA as required by the license in use was found.

^◆ unregister_api_component() [1/2]

template<class T>

Sint32 mi::neuraylib::INeuray::unregister_api_component ( )

inline

Unregisters an API component with the MDL SDK API.

The API component will no longer be accessible via get_api_component().

This template variant requires that the API component was registered under the interface ID of the corresponding interface (which is the case for the template variant of register_api_component()).

Returns

0: Success.
-1: There is no API component registered under the ID T::IID().

^◆ unregister_api_component() [2/2]

virtual Sint32 mi::neuraylib::INeuray::unregister_api_component ( const base::Uuid & uuid )

pure virtual

Unregisters an API component with the MDL SDK API.

The API component will no longer be accessible via get_api_component().

Parameters

uuid	The ID of the API component to unregister.

Returns

0: Success.
-1: There is no API component registered under the ID uuid.
