## 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_get_path ()

    const gchar *
    webkit_user_content_filter_store_get_path
                                   (WebKitUserContentFilterStore *store);

#### Parameters

store | a WebKitUserContentFilterStore |

#### Returns

The storage path for user content filters.

### 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

result | a GAsyncResult |
error | return location for error or `NULL` to ignore |

#### Returns

a WebKitUserContentFilter, or `NULL` if saving failed.
