Method Detail

getSpec

public Spec getSpec()

Description copied from interface: YamcsService

Returns the valid configuration options for this service.

Specified by:

getSpec in interface YamcsService

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:

onTuple

public void onTuple(Stream stream,
                    Tuple t)

Specified by:

onTuple in interface StreamSubscriber

streamClosed

public void streamClosed(Stream stream)

Specified by:

streamClosed in interface StreamSubscriber
