                 PeersManager peersManager,
                 PeerChannelGroup channelGroup)
```
- Method Detail
  - send
```
public CompletableFuture<Void> send(RelayableMessage message)
```
    Sends message to the recipient defined in the message. Throws a MessengerException if sending is not possible (e.g. because no path to the peer exists).
    The method tries to choose the best path to send the message to the recipient. Thus, it first checks whether the recipient can be reached locally. Then it searches for direct connections to the recipient. If there is no direct connection, the message is relayed to the Super Peer.
    
    Parameters:
    
    message - message to be sent
    
    Returns:
    
    a completed future if the message was successfully processed, otherwise an exceptionally future
