Detailed Description

Wrapper to wait for an OLDB Client connection to be ready using Qt signals.

The developer calls OldbClient().sync_connect(), and when the OldbClient instance has been succesfully obtained, signals connection_changed(2) and connected(True) are emitted. This allows UI to wait for the OLDB Client connection.

In case of error, connection_changed(0), disconnected(True) and error_detected(str) are emitted.

While connecting, signal connection_changed(1) is emitted

IMPORTANT OldbClient().async_connect() is not usable at the moment due to limitation on CiiOldbFactory.get_instance. It is commented for the time being.

Constructor & Destructor Documentation

__init__()

def comms.oldb.OldbClient.__init__	(		self,
		QObject	parent = None
	)

Initializes object and logge.

Member Function Documentation

sync_connect()

def comms.oldb.OldbClient.sync_connect

(

self

)

Connects to OLDB synchronously.

This method will block.

   Connected to the OLDB, and notifies using signals of the result of the
   connection attempt.

   @return CiiOldb reference or None if not succesfull

Note

This is a workaround. This should be moved to TaurusCiiAttribute implementation later. Also, a static method needs to be provided that can do the same.
