java.lang.Object

org.ldk.structs.P2PGossipSync

public class P2PGossipSync
extends Object

Receives and validates network updates from peers, stores authentic and relevant data as a network graph. This network graph is then used for routing payments. Provides interface to help with initial routing sync by serving historical announcements. Serves as an [`EventHandler`] for applying updates from [`Event::PaymentPathFailed`] to the [`NetworkGraph`].

public static P2PGossipSync of(NetworkGraph network_graph,
                               Option_AccessZ chain_access,
                               Logger logger)

Creates a new tracker of the actual state of the network of channels and nodes, assuming an existing Network Graph. Chain monitor is used to make sure announced channels exist on-chain, channel data is correct, and that the announcement is signed with channel owners' keys.

add_chain_access

public void add_chain_access(Option_AccessZ chain_access)

Adds a provider used to check new announcements. Does not affect existing announcements unless they are updated. Add, update or remove the provider would replace the current one.

as_RoutingMessageHandler

public RoutingMessageHandler as_RoutingMessageHandler()

Constructs a new RoutingMessageHandler which calls the relevant methods on this_arg. This copies the `inner` pointer in this_arg and thus the returned RoutingMessageHandler must be freed before this_arg is

as_MessageSendEventsProvider

public MessageSendEventsProvider as_MessageSendEventsProvider()

Constructs a new MessageSendEventsProvider which calls the relevant methods on this_arg. This copies the `inner` pointer in this_arg and thus the returned MessageSendEventsProvider must be freed before this_arg is
