Detailed Description

This abstract interface gives access to the MDL SDK API to plugins.

It offers functionality similar to INeuray, but does not allow to start or shutdown the library. On the other hand it allows the registration of user-defined classes.

Member Function Documentation

◆ get_api_component() [1/2]

template<class T>
T * mi::neuraylib::IPlugin_api::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
TThe 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::IPlugin_api::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
uuidThe 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::IPlugin_api::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 change.

◆ get_version()

virtual const char * mi::neuraylib::IPlugin_api::get_version ( ) const
pure virtual

Returns the product version of the MDL SDK library.

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

◆ register_api_component() [1/2]

virtual Sint32 mi::neuraylib::IPlugin_api::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
uuidThe ID of the API component to register, e.g., the interface ID of the corresponding interface.
api_componentThe 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::IPlugin_api::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_componentThe 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().

◆ unregister_api_component() [1/2]

template<class T>
Sint32 mi::neuraylib::IPlugin_api::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::IPlugin_api::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
uuidThe ID of the API component to unregister.
Returns
  • 0: Success.
  • -1: There is no API component registered under the ID uuid.
