Returns : a new librdf_world or NULL on failure librdf_free_worldvoid librdf_free_world (librdf_world *world); Terminate the library and frees all allocated resources. world : redland world object librdf_world_openvoid librdf_world_open (librdf_world *world); Open a created redland world environment. world : redland world object librdf_world_init_mutexvoid librdf_world_init_mutex (librdf_world *world); INTERNAL - Create the world mutex. world : redland world object librdf_world_set_errorvoid librdf_world_set_error (librdf_world *world, void *user_data, librdf_log_level_func error_handler); Set the world error handling function. The function will receive callbacks when the world fails. librdf_world_set_logger() provides richer access to all log messages and should be used in preference. world : redland world object user_data : user data to pass to function error_handler : pointer to the function librdf_world_set_warningvoid librdf_world_set_warning (librdf_world *world, void *user_data, librdf_log_level_func warning_handler); Set the world warning handling function. The function will receive callbacks when the world gives a warning. librdf_world_set_logger() provides richer access to all log messages and should be used in preference. world : redland world object user_data : user data to pass to function warning_handler : pointer to the function librdf_world_set_loggervoid librdf_world_set_logger (librdf_world *world, void *user_data, librdf_log_func log_handler); Set the world log handling function. The function will receive callbacks when redland generates a log message world : redland world object user_data : user data to pass to function log_handler : pointer to the function librdf_world_set_digestvoid librdf_world_set_digest (librdf_world *world, const char *name); Set the default content digest name. Sets the digest factory for various modules that need to make digests of their objects. world : redland world object name : Digest factory name LIBRDF_WORLD_FEATURE_GENID_BASE#define LIBRDF_WORLD_FEATURE_GENID_BASE "http://feature.librdf.org/genid-base" World feature to set the generated ID base. Must be set before the world is opened with librdf_world_open(). LIBRDF_WORLD_FEATURE_GENID_COUNTER#define LIBRDF_WORLD_FEATURE_GENID_COUNTER "http://feature.librdf.org/genid-counter" World feature to set the generated ID counter. Must be set before the world is opened with librdf_world_open(). librdf_world_get_featurelibrdf_node* librdf_world_get_feature (librdf_world *world, librdf_uri *feature); Get the value of a world feature. world : librdf_world object feature : librdf_uri feature property Returns : new librdf_node feature value or NULL if no such feature exists or the value is empty. librdf_world_set_featureint librdf_world_set_feature (librdf_world *world, librdf_uri *feature, librdf_node *value); Set the value of a world feature. world : librdf_world object feature : librdf_uri feature property value : librdf_node feature property value Returns : non 0 on failure (negative if no such feature) librdf_init_worldvoid librdf_init_world (char *digest_factory_name, void *not_used2); Initialise the library deprecated: Do not use. Use librdf_new_world() and librdf_world_open() on librdf_world object See librdf_world_set_digest_factory_name() for documentation on arguments. digest_factory_name : Name of digest factory to use not_used2 : Not used librdf_destroy_worldvoid librdf_destroy_world (void); Terminate the library deprecated: Do not use. Use librdf_free_world() on librdf_world object Terminates and frees the resources.
