Function Documentation

◆ playerc_vectormap_cleanup()

PLAYERC_EXPORT void playerc_vectormap_cleanup ( playerc_vectormap_t device)

Clean up the dynamically allocated memory for the vectormap.

◆ playerc_vectormap_create()

PLAYERC_EXPORT playerc_vectormap_t* playerc_vectormap_create ( playerc_client_t client,
int  index 
)

Create a vectormap proxy.

◆ playerc_vectormap_destroy()

PLAYERC_EXPORT void playerc_vectormap_destroy ( playerc_vectormap_t device)

Destroy a vectormap proxy.

◆ playerc_vectormap_get_feature_data()

PLAYERC_EXPORT uint8_t* playerc_vectormap_get_feature_data ( playerc_vectormap_t device,
unsigned  layer_index,
unsigned  feature_index 
)

Get an individual feature as a WKB geometry.

Must only be used after a successful call to playerc_vectormap_get_layer_data. The WKB geometry is owned by the proxy, duplicate it if it is needed after the next call to get_feature_data.

◆ playerc_vectormap_get_layer_data()

PLAYERC_EXPORT int playerc_vectormap_get_layer_data ( playerc_vectormap_t device,
unsigned  layer_index 
)

Get the layer data by index.

Must only be used after a successfull call to playerc_vectormap_get_map_info.

◆ playerc_vectormap_get_map_info()

PLAYERC_EXPORT int playerc_vectormap_get_map_info ( playerc_vectormap_t device)

Get the vectormap metadata, which is stored in the proxy.

◆ playerc_vectormap_subscribe()

PLAYERC_EXPORT int playerc_vectormap_subscribe ( playerc_vectormap_t device,
int  access 
)

Subscribe to the vectormap device.

◆ playerc_vectormap_unsubscribe()

PLAYERC_EXPORT int playerc_vectormap_unsubscribe ( playerc_vectormap_t device)

Un-subscribe from the vectormap device.

◆ playerc_vectormap_write_layer()

PLAYERC_EXPORT int playerc_vectormap_write_layer ( playerc_vectormap_t device,
const player_vectormap_layer_data_t data 
)

Write layer data.
