resolvePeerId method

Iterable<FullAddress> resolvePeerId(PeerId peerId)

Resolves a Peer ID to a set of network addresses.

This method attempts to find the network addresses associated with a given Peer ID. If the Peer ID is known and has a route, the method returns the actual addresses associated with the route, filtering out stale addresses based on the peerAddressTTL.

If the Peer ID is unknown or has no route, the method returns the addresses of forwarder peers that can potentially relay messages to the target peer. The number of forwarder addresses returned is limited by the useForwardersLimit property.

peerId The ID of the peer to resolve.

Returns an iterable of FullAddress objects representing the resolved addresses.

Implementation

Iterable<FullAddress> resolvePeerId(PeerId peerId) {
  final route = routes[peerId];

  if (route == null || route.isEmpty) {
    final result = <FullAddress>{};

    for (final a in routes.values.where((e) => e.canForward)) {
      result.addAll(a.addresses.keys);
    }

    return result.take(useForwardersLimit);
  } else {
    return route.getActualAddresses(
      staleAt: _now - peerAddressTTL.inMilliseconds,
    );
  }
}
