# bokeh.client.connection

Implements a very low level facility for communicating with a Bokeh Server.

Users will always want to use `ClientSession` instead for standard usage.

class `bokeh.client.connection.` `ClientConnection`(session, websocket_url, io_loop=None)

  A Bokeh low-level class used to implement ClientSession; use ClientSession to connect to the server.

  `close`(why='closed')

    Close the Websocket connection.

  `force_roundtrip`()

    Force a round-trip request/reply to the server, sometimes needed to avoid race conditions. Mostly useful for testing.

    Outside of test suites, this method hurts performance and should not be needed.

    Returns: | None

  `loop_until_closed`()

    Execute a blocking loop that runs and exectutes event callbacks until the connection is closed (e.g. by hitting Ctrl-C).

    While this method can be used to run Bokeh application code “outside” the Bokeh server, this practice is HIGHLY DISCOURAGED for any real use case.

  `pull_doc`(document)

    Pull a document from the server, overwriting the passed-in document

    Parameters: | document – (Document) The document to overwrite with server content.
    Returns: | None

  `push_doc`(document)

    Push a document to the server, overwriting any existing server-side doc.

    Parameters: | document – (Document) A Document to push to the server
    Returns: | The server reply

  `request_server_info`()

    Ask for information about the server.

    Returns: | A dictionary of server attributes.

  `connected`

    Whether we’ve connected the Websocket and have exchanged initial handshake messages.

  `io_loop`

    The Tornado `IOLoop` this connection is using.

  `url`

    The URL of the websocket this Connection is to.
