virtual Sint32 mi::​neuraylib::​IExtension_api::register_call_decl( const char* call_name, const ICall_decl* decl) [pure virtual]

Registers a call declaration with the neuray API. Note that the type names of the call members are not checked for validity here (except for cycles). Thus, it is possible that this methods succeeds, but creating an instance of the type call_name will fail.

Parameters

call_name

The name to be used to refer to this call declaration. The name must consist only of alphanumeric characters or underscores, must not start with an underscore, and must not be the empty string.

decl

The call declaration. The declaration is internally cloned such that subsequent changes have no effect on the registered declaration.

Returns

• 0: Success.
• -1: There is already a class, structure, enum, or call declaration registered under the name call_name.
• -2: Invalid parameters (NULL pointer).
• -4: Invalid name for a call declaration.
• -5: A registration under the name call_name would cause an infinite cycle of nested call types.

virtual Sint32 mi::​neuraylib::​IExtension_api::register_class( const char* class_name, base::​Uuid uuid, IUser_class_factory* factory) [pure virtual]

Registers a class with the neuray API. All user-defined classes to be used with the neuray API must be registered. The only exception are classes that never cross the API boundary, for example, classes only used locally within a plugin. Class registration must be done before has been started or in mi::neuraylib::IPlugin::init().

Parameters

class_name

The class name under which the class is to be registered. The class name must consist only of alphanumeric characters or underscores, must not start with an underscore, and must not be the empty string.

uuid

The class ID of the class. You can simply pass IID() of your class derived from mi::neuraylib::User_class.

factory

The factory method of the class.

Returns

• 0: Success.
• -1: There is already a class or structure declaration registered under the name class_name or UUID uuid.
• -2: Invalid parameters (NULL pointer).
• -3: The method may not be called at that point of time.
• -4: Invalid class name.

Sint32 mi::​neuraylib::​IExtension_api::register_class( const char* class_name) [inline]

Registers a class with the neuray API. All user-defined classes to be used with the neuray API must be registered. The only exception are classes that never cross the API boundary, for example, classes only used locally within a plugin. Class registration must be done before has been started or in mi::neuraylib::IPlugin::init().

This templated member function is a wrapper of the non-template variant for the user's convenience. It uses the default class factory mi::neuraylib::User_class_factory specialized for T.

Parameters

class_name

The class name under which the class is to be registered. The class name must consist only of alphanumeric characters or underscores, must not start with an underscore, and must not be the empty string.

Returns

• 0: Success.
• -1: There is already a class or structure declaration registered under the name class_name or UUID T::IID().
• -2: Invalid parameters (NULL pointer).
• -3: The method may not be called at that point of time.
• -4: Invalid class name.

virtual Sint32 mi::​neuraylib::​IExtension_api::register_enum_decl( const char* enum_name, const IEnum_decl* decl) [pure virtual]

Registers an enum declaration with the neuray API.

Parameters

enum_name

The name to be used to refer to this enum declaration. The name must consist only of alphanumeric characters or underscores, must not start with an underscore, and must not be the empty string.

decl

The enum declaration. The declaration is internally cloned such that subsequent changes have no effect on the registered declaration.

Returns

• 0: Success.
• -1: There is already a class, structure, enum, or call declaration registered under the name enum_name.
• -2: Invalid parameters (NULL pointer).
• -4: Invalid name for an enum declaration.
• -6: The enum declaration is empty and therefore invalid.

virtual Sint32 mi::​neuraylib::​IExtension_api::register_exporter( IExporter* exporter) [pure virtual]

Registers a new exporter with the neuray API. Exporter registration must be done before has been started or in mi::neuraylib::IPlugin::init().

Parameters

exporter

The new exporter to register.

Returns

• 0: Success.
• -1: Invalid parameters (NULL pointer).
• -2: The method may not be called at that point of time.

virtual Sint32 mi::​neuraylib::​IExtension_api::register_importer( IImporter* importer) [pure virtual]

Registers a new importer with the neuray API. Importer registration must be done before has been started or in mi::neuraylib::IPlugin::init().

Parameters

importer

The new importer to register.

Returns

• 0: Success.
• -1: Invalid parameters (NULL pointer).
• -2: The method may not be called at that point of time.

virtual Sint32 mi::​neuraylib::​IExtension_api::register_structure_decl( const char* structure_name, const IStructure_decl* decl) [pure virtual]

Registers a structure declaration with the neuray API. Note that the type names of the structure members are not checked for validity here (except for cycles). Thus, it is possible that this methods succeeds, but creating an instance of the type structure_name will fail.

Parameters

structure_name

The name to be used to refer to this structure declaration. The name must consist only of alphanumeric characters or underscores, must not start with an underscore, and must not be the empty string.

decl

The structure declaration. The declaration is internally cloned such that subsequent changes have no effect on the registered declaration.

Returns

• 0: Success.
• -1: There is already a class, structure, enum, or call declaration registered under the name structure_name.
• -2: Invalid parameters (NULL pointer).
• -4: Invalid name for a structure declaration.
• -5: A registration under the name structure_name would cause an infinite cycle of nested structure types.
