Description

This factory manages the create of ChamplainMapSource. It contains names and constructor functions for each available map sources in libchamplain. You can add your own with champlain_map_source_factory_register.

To get the wanted map source, use champlain_map_source_factory_create. It will return a ready to use ChamplainMapSource.

To get the list of registered map sources, use champlain_map_source_factory_dup_list.

Details

typedef struct _ChamplainMapSourceFactory ChamplainMapSourceFactory;


champlain_map_source_factory_dup_default ()

ChamplainMapSourceFactory * champlain_map_source_factory_dup_default
                                                        (void);

A method to obtain the singleton object.

Returns :

the singleton ChamplainMapSourceFactory, it should be freed using g_object_unref when not needed.

Since 0.4


champlain_map_source_factory_dup_list ()

GSList *            champlain_map_source_factory_dup_list
                                                        (ChamplainMapSourceFactory *factory);

Get the list of registered map sources.

factory :

the Factory

Returns :

the list of registered map sources, the items should not be freed, the list should be freed with g_slist_free.

Since 0.4


champlain_map_source_factory_create ()

ChamplainMapSource * champlain_map_source_factory_create
                                                        (ChamplainMapSourceFactory *factory,
                                                         const gchar *id);

The id should not contain any character that can't be in a filename as it will be used as the cache directory name for that map source.

factory :

the Factory

id :

the wanted map source id

Returns :

a ready to use ChamplainMapSource matching the given name, returns NULL is none match.

Since 0.4


champlain_map_source_factory_create_cached_source ()

Creates a cached map source.

factory :

the Factory

id :

the wanted map source id

Returns :

a ready to use ChamplainMapSourceChain consisting of ChamplainMemoryCache, ChamplainFileCache, ChamplainMapSource matching the given name, and an error tile source created with champlain_map_source_factory_create_error_source().

Since 0.6


champlain_map_source_factory_create_error_source ()

ChamplainMapSource * champlain_map_source_factory_create_error_source
                                                        (ChamplainMapSourceFactory *factory,
                                                         guint tile_size);

Creates a map source generating error tiles.

factory :

the Factory

tile_size :

the size of the error tile

Returns :

a ready to use map source generating error tiles.

Since 0.8


champlain_map_source_factory_register ()

gboolean            champlain_map_source_factory_register
                                                        (ChamplainMapSourceFactory *factory,

                                                         ChamplainMapSourceConstructor constructor,
                                                         gpointer data);

Registers the new map source with the given constructor. When this map source is requested, the given constructor will be used to build the map source. ChamplainMapSourceFactory will take ownership of the passed ChamplainMapSourceDesc, so don't free it. They will not be freed either so you can use static structs here.

factory :

A ChamplainMapSourceFactory

desc :

the description of the map source

constructor :

the new map source constructor function

data :

data to be passed to the constructor function, or NULL

Returns :

TRUE if the registration suceeded.
