Functions definitionsWhen using the jQuery.atmosphere.js or atmosphere.js Javascript client, you have several functions you can set in order to get notified when events occurs:
-
onOpen:
- onOpen will be called for all transports when the connection is fully established.
-
onClose: The onClose is called when:
- an error occurs.
- when the server or a proxy closes the connection.
- when an expected exception occurs.
- when the specified transport is not supported or fail to connect.
-
onMessage: Everytime a new message is received
-
onError: The onError is called when:
- the request.maxReconnectOnClose re-connect try has failed
- an unexpected error occured.
-
onTransportFailure: if the specified transport fails to connect, this function will be called before the reconnect, with the fallbackTransport.
-
onClientTimeout: if the request.timeout expires, this function will be called, allowing an application to reconnect if needed.
-
onReconnect:
- Every time an error happens and a reconnect needs to happens. This works for all transport, e.g for long-polling, onReconnect will only be called if an error happens and never before reconnecting.
-
onReopen: this function is called every time a re-connection successfully reconnected.
-
onMessagePublished: Except for websockets, the onMessagePublished will be invoked when a POST is made and the server side is sending a response using the 'polling' connection.
Possible workflow
onOpen -> onMessage -> onClose // Normal
onTransportFailure -> onOpen -> onMessage -> onClose // transport not supported
onOpen -> onMessage -> [connection closed] -> onReconnect -> onClose -> onError // maxReconnectOnClose
onOpen -> onMessage -> [connection closed] -> onReconnect -> onMessage
onOpen -> [request.timeout expires] -> onClientTimeout
