Description

The WebKitUserContentFilterStore provides the means to import and save JSON rule sets, which can be loaded later in an efficient manner. Once filters are stored, the WebKitUserContentFilter objects which represent them can be added to a WebKitUserContentManager with webkit_user_content_manager_add_filter().

JSON rule sets are imported using webkit_user_content_filter_store_save() and stored on disk in an implementation defined format. The contents of a filter store must be managed using the WebKitUserContentFilterStore: a list of all the stored filters can be obtained with webkit_user_content_filter_store_fetch_identifiers(), webkit_user_content_filter_store_load() can be used to retrieve a previously saved filter, and removed from the store with webkit_user_content_filter_store_remove().

Functions

webkit_user_content_filter_store_new ()

WebKitUserContentFilterStore *
webkit_user_content_filter_store_new (const gchar *storage_path);

Create a new WebKitUserContentFilterStore to manipulate filters stored at storage_path . The path must point to a local filesystem, and will be created if needed.

Parameters

storage_path

path where data for filters will be stored on disk

Returns

a newly created WebKitUserContentFilterStore.

webkit_user_content_filter_store_save ()

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

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.

Parameters

store	a WebKitUserContentFilterStore
identifier	a string used to identify the saved filter
source	GBytes containing the rule set in JSON format
cancellable	a GCancellable or `NULL` to ignore.	[allow-none]
callback	a GAsyncReadyCallback to call when saving is completed.	[scope async]
user_data	the data to pass to the callback function.	[closure]

                                GError **error);

Finishes an asynchronous filter save previously started with webkit_user_content_filter_store_save().

Parameters
