librdf_world

typedef struct librdf_world_s librdf_world;

Redland world class.

librdf_new_world ()

librdf_world *      librdf_new_world                    (void);

Create a new Redland execution environment.

Once this constructor is called to build a librdf_world object several functions may be called to set some parameters such as librdf_world_set_error(), librdf_world_set_warning(), librdf_world_set_logger(), librdf_world_set_digest(), librdf_world_set_feature().

The world object needs initializing using librdf_world_open() whether or not the above functions are called. It will be automatically called by all object constructors in Redland 1.0.6 or later, but for earlier versions it MUST be called before using any other part of Redland.

librdf_free_world ()

void                librdf_free_world                   (librdf_world *world);

Terminate the library and frees all allocated resources.

librdf_world_open ()

void                librdf_world_open                   (librdf_world *world);

Open a created redland world environment.

librdf_world_set_rasqal ()

void                librdf_world_set_rasqal             (librdf_world *world,

Set the rasqal_world instance to be used with this librdf_world.

If no rasqal_world instance is set with this function, librdf_world_open() creates a new instance.

Ownership of the rasqal_world is not taken. If the rasqal library instance is set with this function, librdf_free_world() will not free it.

librdf_world_get_rasqal ()

rasqal_world *      librdf_world_get_rasqal             (librdf_world *world);

Get the rasqal_world instance used by this librdf_world.

Get the raptor_world instance used by this librdf_world.

Set the raptor_world instance to be used with this librdf_world.

If no raptor_world instance is set with this function, librdf_world_open() creates a new instance.

Ownership of the raptor_world is not taken. If the raptor library instance is set with this function, librdf_free_world() will not free it.

librdf_world_init_mutex ()

void                librdf_world_init_mutex             (librdf_world *world);

INTERNAL - Create the world mutex.

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.

librdf_world_set_logger ()
