Method

MaplibreNativeFfiMapset_style_source_volatile_async

Declaration [src] 

void
maplibre_native_ffi_map_set_style_source_volatile_async (
  MaplibreNativeFfiMap* self,
  const char* source_id,
  gboolean is_volatile,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Sets whether a source is volatile.

The map doesn’t store the tiles of a volatile source in the persistent cache.

See mln_map_set_style_source_volatile in the C API reference.

It fails with these errors:

  • MAPLIBRE_NATIVE_FFI_ERROR_NOT_FOUND when the style has no source named source_id.
  • MAPLIBRE_NATIVE_FFI_ERROR_INVALID_STATE while the style isn’t loaded, as maplibre_native_ffi_map_set_style_url_async() describes.

Without callback, nothing reports whether the call succeeds.

This method completes asynchronously. Use maplibre_native_ffi_map_set_style_source_volatile_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
