Class LinkManager

java.lang.Object

org.yamcs.management.LinkManager

public class LinkManager
extends Object

Service that manages all the data links

Compared to the old DataLinkInitializer this one:

• is the endpoint for the /links API calls
• takes care for the commanding links to subscribe/unsubscribe them from the streams whenever they are enabled/disabled
• TODO: can set exclusive flags - i.e. only one link from a group can be enabled at a time

The configuration of this service is done in the "dataLinks" sections of the yamcs.<instance-name>.yaml file.
