### Method

# WebKit UserContentFilterStore save

since: 2.24

#### Declaration [src]

    void
    webkit_user_content_filter_store_save (
      WebKitUserContentFilterStore* store,
      const gchar* identifier,
      GBytes* source,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Asynchronously save a content filter from a set source rule.

Asynchronously save a content filter from a source rule set in the WebKit content extesions JSON format.

The `identifier` can be used afterwards to refer to the filter when using `webkit_user_content_filter_store_remove()` and webkit_user_content_filter_store_load(). When the `identifier` has been used in the past, the new filter source will replace the one saved beforehand for the same identifier.

When the operation is finished, `callback` will be invoked, which then can use `webkit_user_content_filter_store_save_finish()` to obtain the resulting filter.
