                                             throws LiveViewException

Retrieves a LiveViewMultiConnection based on the given MultiConnectionConfig. Note that this call has no declared exceptions, as errors connecting to individual servers are handled internally and available as statuses for each underlying LiveViewConnectionControl.

Important: see the Javadoc for LiveViewMultiConnection for limitations to expect when connect to servers this way.

Parameters:

config - configuration, identifying the servers you want to connect to, plus some flags that control how you connect

waitForConnection - true if you want to wait until at least one connection is made before this call returns. If false, this method returns immediately although many operations will throw an exception until a connection is later established.

Returns:

LiveViewMultiConnection the connection object

Throws:

LiveViewException - may be thrown on errors. Note that most errors will be reported using the listeners attached to the configuration instead.
