Class ReplicationServer

java.lang.Object

com.google.common.util.concurrent.AbstractService

org.yamcs.AbstractYamcsService

org.yamcs.replication.ReplicationServer

All Implemented Interfaces:

com.google.common.util.concurrent.Service, YamcsService

public class ReplicationServer
extends AbstractYamcsService

TCP replication server - works both on the master and on the slave side depending on the channel handler

Has to be defined as a global Yamcs service. The ReplicationMaster or ReplicationSlave defined at the instance level will register to this if the tcpRole is set to "Server".

ReplicationServer

public ReplicationServer()

Method Details

getSpec

public Spec getSpec()

Description copied from interface: YamcsService

Returns the valid configuration options for this service.

Returns:

the argument specification, or null if the args should not be validated.

init

public void init(String yamcsInstance,
 String serviceName,
 YConfiguration config)
          throws InitException

Description copied from interface: YamcsService

Initialize this service. This is called before the service is started. All operations should finish fast.

Specified by:

init in interface YamcsService

Overrides:

init in class AbstractYamcsService

Parameters:

yamcsInstance - The yamcs instance, or null if this is a global service.

serviceName - The service name.

config - The configured arguments for this service. If YamcsService.getSpec() is implemented then this contains the arguments after being validated (including any defaults).

Throws:

InitException - When something goes wrong during the execution of this method.

doStart

protected void doStart()

Specified by:

doStart in class com.google.common.util.concurrent.AbstractService

doStop

protected void doStop()

Specified by:

doStop in class com.google.common.util.concurrent.AbstractService
