Method Detail

getLinkStatus

Link.Status getLinkStatus()

Returns the current link status.

getDetailedStatus

default String getDetailedStatus()

Returns:

more detailed status information

enable

void enable()

Reenable the data transit if disabled by the disable() method.

disable

void disable()

Disable any data I/O through this link. Any connection to a server is closed. Can be reenabled using the enable method. Note that this method can be called before starting the service if it's configured as such in the configuration file

isDisabled

boolean isDisabled()

getDataInCount

long getDataInCount()

getDataOutCount

long getDataOutCount()

resetCounters

void resetCounters()

getName

String getName()

Return the name of the link

getConfig

YConfiguration getConfig()

Returns:

the config (args) used when creating the link

getParent

default AggregatedDataLink getParent()

If this link is a sublink of an aggregated link, get the parent link.

setParent

default void setParent(AggregatedDataLink parent)

Set the parent link if this is a sublink of an aggregated link.

setupSystemParameters

default void setupSystemParameters(SystemParametersCollector sysParamCollector)

Called by the LinkManager before startup if the SystemParametersCollector service is enabled, to setup necessary things for later parameter collection.

The method is called only on the links that implement the SystemParametersProducer interface; they are also registered with the SystemParametersCollector to be called regularly after the start.

init

default void init(String yamcsInstance,
                  String linkName,
                  YConfiguration config)

Called at startup to initialize the link.

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

Parameters:

yamcsInstance -

linkName -

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

getSpec

default Spec getSpec()

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

Returns:

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