Detailed Description

template<class T>
class mi::neuraylib::User_class_factory< T >

This mixin class provides a default implementation of the IUser_class_factory interface.

This default implementation of mi::neuraylib::IUser_class_factory simply calls the default constructor of T without arguments.

The default implementation is used implicitly by some variants of the class registration, see mi::neuraylib::IExtension_api::register_class(const char*).

Member Function Documentation

template<class T >

base::IInterface* mi::neuraylib::User_class_factory< T >::create ( ITransaction *  transaction, Uint32  argc, const base::IInterface *  argv[]  )

inlinevirtual

Creates an instance of the class for which the factory was registered.

This default implementation simply calls the default constructor of T without arguments. It does not accept any parameters, i.e., it requires argc = 0.

Parameters

transaction	The transaction (ignored).
argc	The size of the argv array (must be 0).
argv	An array of optional arguments (ignored).

Returns

An instance of the class, or NULL on failure.

Implements mi::neuraylib::IUser_class_factory.
