Package org.yamcs.archive

Class ParameterRecorder

java.lang.Object

com.google.common.util.concurrent.AbstractService

org.yamcs.AbstractYamcsService

org.yamcs.archive.ParameterRecorder

All Implemented Interfaces:

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

public class ParameterRecorder
extends AbstractYamcsService

ParameterRecorder Records (processed) Parameters

This records parameters as tuples - good for realtime recording but not very efficient for retrieval of a few parameters over long time periods.

The org.yamcs.parameterarchive records parameters in a columnar fashion - not good for realtime but much more efficient for retrieval especially retrieval of few parameters over long time periods.

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
