public TcpTmDataLink()

Method Details

getSpec

public Spec getSpec()

Description copied from interface: Link

Returns the valid configuration of the input args of this link.

Specified by:

getSpec in interface Link

Returns:

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

init

public void init(String instance,
 String name,
 YConfiguration config)
          throws ConfigurationException

Description copied from interface: Link

Called at startup to initialize the link.

The config corresponds to the map that is under the link definition in yamcs.instance.yaml.

Specified by:

init in interface Link

Overrides:

init in class AbstractTmDataLink

config - - the configuration - cannot be null (but can be empty)

Throws:

ConfigurationException

                   throws IOException

Throws:

IOException

doStart

public void doStart()

Specified by:

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

doStop

public void doStop()

Specified by:

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

run

public void run()

Specified by:

run in interface Runnable

getNextPacket

public TmPacket getNextPacket()

doDisable

public void doDisable()

Overrides:

doDisable in class AbstractLink

doEnable

public void doEnable()

Overrides:

doEnable in class AbstractLink

getDetailedStatus

public String getDetailedStatus()

Description copied from interface: Link

Returns a short detail status (one-line)

Specified by:

getDetailedStatus in interface Link

Overrides:

getDetailedStatus in class AbstractLink

connectionStatus

protected Link.Status connectionStatus()

Description copied from class: AbstractLink

In case the link should be connected (i.e. is running and enabled) this method is called to return the actual connection status

Specified by:

connectionStatus in class AbstractLink
