Constructor Details

#initialize(attributes = {}) ⇒ ConnectionDetails

Returns a new instance of ConnectionDetails.

Parameters:

  • attributes (Hash) (defaults to: {})

Options Hash (attributes):

  • :client_id (String) —

    Contains the client ID assigned to the token. If clientId is null or omitted, then the client is prohibited from assuming a clientId in any operations, however if clientId is a wildcard string *, then the client is permitted to assume any clientId. Any other string value for clientId implies that the clientId is both enforced and assumed for all operations from this client.

  • :connection_key (String) —

    the connection secret key string that is used to resume a connection and its state

  • :max_message_size (Integer) —

    maximum individual message size in bytes

  • :max_frame_size (Integer) —

    maximum size for a single frame of data sent to Ably. This restriction applies to a ProtocolMessage sent over a realtime connection, or the total body size for a REST request

  • :max_inbound_rate (Integer) —

    maximum allowable number of requests per second from a client

  • :max_idle_interval (Integer) —

    is the maximum length of time in seconds that the server will allow no activity to occur in the server->client direction. After such a period of inactivity, the server will send a @HEARTBEAT@ or transport-level ping to the client. If the value is 0, the server will allow arbitrarily-long levels of inactivity.

  • :connection_state_ttl (Integer) —

    duration in seconds that Ably will persist the connection state when a Realtime client is abruptly disconnected

  • :server_id (String) —

    unique identifier of the Ably server where the connection is established
