Constant Field Values

needsHostConnection

public boolean needsHostConnection

Whether we should continue to accept messages from the "hostWrapper" even if the "equipmentWrapper" has closed. The default for voyeur is false, that is, we will continue to extract information even if we have nowhere to send the messages. This could result in a large number of T3 and it is the responibility of whoever is extracting the information to deal with this. This may simply be to ignore them and hope that the equipment can handle it, or respond to the messages and ignore the host, or spool the messages of whatever.
