public class ChannelMessageHandler extends Object
A trait to describe an object which can receive channel messages. Messages MAY be called in parallel when they originate from different `their_node_ids`, however they MUST NOT be called in parallel when the two calls have the same `their_node_id`.

Method Detail
-
finalize
protected void finalize() throws Throwable
-
destroy
public void destroy()
Destroys the object, freeing associated resources. After this call, any access to this object may result in a SEGFAULT or worse. You should generally NEVER call this method. You should let the garbage collector do this for you when it finalizes objects. However, it may be useful for types which represent locks and should be closed immediately to avoid holding locks until the GC runs.

-
peer_disconnected
public void peer_disconnected(byte[] their_node_id)

-
peer_connected
public Result_NoneNoneZ peer_connected(byte[] their_node_id, Init msg, boolean inbound)
Handle a peer reconnecting, possibly generating `channel_reestablish` message(s). May return an `Err(())` if the features the peer supports are not sufficient to communicate with us. Implementors should be somewhat conservative about doing so, however, as other message handlers may still wish to communicate with this peer.
-
handle_channel_reestablish
public void handle_channel_reestablish(byte[] their_node_id, ChannelReestablish msg)
Handle an incoming `channel_reestablish` message from the given peer.

Handle an incoming `channel_update` message from the given peer.
-
handle_error
public void handle_error(byte[] their_node_id, ErrorMessage msg)
Handle an incoming `error` message from the given peer.
-
provided_node_features
public NodeFeatures provided_node_features()
Gets the node feature flags which this handler itself supports. All available handlers are queried similarly and their feature flags are OR'd together to form the [`NodeFeatures`] which are broadcasted in our [`NodeAnnouncement`] message.
-
provided_init_features
public InitFeatures provided_init_features(byte[] their_node_id)
Gets the init feature flags which should be sent to the given peer. All available handlers are queried similarly and their feature flags are OR'd together to form the [`InitFeatures`] which are sent in our [`Init`] message. Note that this method is called before [`Self::peer_connected`].
