Member Function Documentation

def lookup (    port,   server )

Static method for resolving the multicast port and group values. Parameters: port  An integer containing the multicast port to use, e.g. from the port() method above, or None to indicate that the value will come from the supplied server string. server  A string that contains either the machine ID (test stand instance number), or <port><group IP or name>, or <group ip ="" or="" name>=""> when a port number is also supplied. These last two can be used to override the values chosen by this class. The machine ID is a number from 0 - 999, where the hundreds digit represents the site ID and remainder (0-99) is the machine ID at the site. This latter portion is what's used. Returns: A list made up of the resolved port and group values. Definition at line 268 of file DataDistributor.py.

def port (    name  )

Static method to select a physical multicast port to use based on the type of data that is desired. Parameters: name  The name of the type of data that is desired. Choose from 'LAT_EBFdata', 'LAT_CMDdata', 'LAT_HSKdata' and 'LAT_MsgLog'. Definition at line 257 of file DataDistributor.py.
