## Description

GFBGraphNode is the base class for the nodes in the Facebook Graph API, such a Album, a Photo or a User. Only usefull to expand the current library functionality creating new nodes based on it.

This object provide the common functions to manage the relations between nodes trough the GFBGraphConnectable interface. See gfbgraph_node_get_connection_nodes and gfbgraph_node_append_node

### gfbgraph_node_get_connection_nodes ()

    GList *
    gfbgraph_node_get_connection_nodes (GFBGraphNode *node,

                                        GError **error);

Retrieve the nodes of type `node_type` connected to the `node` object. The `node_type` object must implement the GFBGraphConnectionable interface and be connectable to `node` type object. See `gfbgraph_node_get_connection_nodes_async()` for the asynchronous version of this call.

#### Parameters

node | a GFBGraphNode object which retrieve the connected nodes. |
node_type | a GFBGraphNode type GType that determines the kind of nodes to retrieve. |
authorizer | a GFBGraphAuthorizer. |
error | a GError or `NULL`. | [allow-none]

#### Returns

a newly-allocated GList of type `node_type` objects with the found nodes.

### gfbgraph_node_get_connection_nodes_async ()

    void
    gfbgraph_node_get_connection_nodes_async
                                   (GFBGraphNode *node,
                                    GType node_type,
                                    GFBGraphAuthorizer *authorizer,
                                    GCancellable *cancellable,
                                    GAsyncReadyCallback callback,
                                    gpointer user_data);

Asynchronously retrieve the list of nodes of type `node_type` connected to the `node` object. See `gfbgraph_node_get_connection_nodes()` for the synchronous version of this call.

When the operation is finished, `callback` will be called. You can then call `gfbgraph_node_get_connection_nodes_finish()` to get the list of connected nodes.

#### Parameters

node | A GFBGraphNode object which retrieve the connected nodes. |
node_type | a GFBGraphNode type GType that must implement the GFBGraphConnectionable interface. |
authorizer | a GFBGraphAuthorizer. |
cancellable | An optional GCancellable object, or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is completed. | [scope async]
user_data | The data to pass to `callback` . | [closure]

### gfbgraph_node_get_connection_nodes_async_finish ()

    GList *
    gfbgraph_node_get_connection_nodes_async_finish
                                   (GFBGraphNode *node,
                                    GAsyncResult *result,
                                    GError **error);

Finishes an asynchronous operation started with `gfbgraph_node_get_connection_nodes_async()`.

#### Parameters

node | A GFBGraphNode. |
result | A GAsyncResult. |
error | An optional GError, or `NULL`. | [allow-none]

#### Returns

a newly-allocated GList of type node_type objects with the found nodes.
