Package org.yamcs.ygw

Class YgwParameterManager

java.lang.Object

org.yamcs.ygw.YgwParameterManager

All Implemented Interfaces:

SoftwareParameterManager

public class YgwParameterManager
extends Object
implements SoftwareParameterManager

Handles parameter updates from the clients.

When a YgwLink is configured, one instance of this is created and registered to the realtime processor of the Yamcs instance where the link belongs.

Objects of this class are linked to the processor so they may be used by multiple gateways. Each gateway should configure their own namespace to avoid clashing of parameters.
