public ReplicationSlave()

Method Details

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.

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.

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

getStreamNames

public List<String> getStreamNames()

isTcpClient

public boolean isTcpClient()

getTcpClient

public ReplicationClient getTcpClient()

getMasterHost

public String getMasterHost()

getMasterPort

public int getMasterPort()

getMasterInstance

public String getMasterInstance()

getTxId

public long getTxId()

newChannelHandler

public io.netty.channel.ChannelHandler newChannelHandler()
                                                  throws YamcsException

Called when the tcpRole = Server and a new client connects to ReplicationServer

Throws:

YamcsException - if there is already a connection open to this slave
