Server

Interface which duplicates AIDL Server-side interface

In terms of NEXO Projects:

• Server is a listener, which wait for commands from Client to handle and response to Client

• Client is initiator which can send commands to Server and handles responses

Communication flow looks like this:

    Client[process A] Server[process B]
    1. Client ─── connect ──► Server "saves it's reference on side of process A"
    2. Server ◄── bind ─── Client "saves it's reference on side of process B"
    3. Client ─── calls ──► Server::onMessage
    4. Server ─── handles message: String ──► Result ──┐
                                                       │
    5.                                   [calls ──► Client::onMessage]
                                                       │
    6.                           Responses to client◄──┘

Reconnection flow has two cases:

1. Connection was not established from first connecting
2. Connection was lost during communication

There are two types of policy of resolving this issue:

• Reset - resets the connection

• Reconnect - tries to reconnect to server again with configurable amounts of tries with configured timeouts

• For Reconnection flow 1 - default policy Reset

• For Reconnection flow 2 - default policy Reconnect. If after retries connection was not re-established, Client will try to connect to Server when it have new command
