Member Function Documentation

get_plugin_descriptor()

virtual base::IPlugin_descriptor * mi::neuraylib::IPlugin_configuration::get_plugin_descriptor ( Size  index ) const

pure virtual

Returns a descriptor for the index -th loaded plugin.

Returns

A descriptor for the index -th loaded plugin, or NULL in case of failure.

get_plugin_length()

virtual Size mi::neuraylib::IPlugin_configuration::get_plugin_length ( ) const

pure virtual

Returns the number of loaded plugins.

Returns

The number of loaded plugins.

load_plugin_library()

virtual Sint32 mi::neuraylib::IPlugin_configuration::load_plugin_library ( const char *  path )

pure virtual

Loads a plugin library.

This function loads the specified shared library, enumerates all plugin classes in the specified shared library, and adds them to the system.

This function can only be called before the MDL SDK has been started.

Parameters

path	The path of the shared library to be loaded. This shared library needs to be a valid plugin for the MDL SDK.

Returns

0, in case of success, -1 in case of failure.

load_plugins_from_directory()

virtual Sint32 mi::neuraylib::IPlugin_configuration::load_plugins_from_directory ( const char *  path )

pure virtual

Loads all plugins from a given directory.

Enumerates all plugins in the given directory in alphabetic order and calls load_plugin_library() for each of them in turn. On Windows, all files with the extension .dll are considered, while on Linux and MacOS X all files with the extension .so are considered. Additionally, on MacOS X all files with extension .dylib are considered.

Parameters

path	The path of the directory.

Returns

0, in case of success, -1 in case of failure.
