Package org.yamcs.parameter

Class LocalParameterManager

java.lang.Object

com.google.common.util.concurrent.AbstractService

org.yamcs.AbstractProcessorService

org.yamcs.parameter.LocalParameterManager

All Implemented Interfaces:

com.google.common.util.concurrent.Service, ParameterProvider, SoftwareParameterManager, ProcessorService

public class LocalParameterManager
extends AbstractProcessorService
implements SoftwareParameterManager, ParameterProvider

Implements software parameters - these are parameters that can be set from the clients. All the parameters are sent from the executor thread.

Method Detail

init

public void init(Processor proc,
                 YConfiguration config,
                 Object spec)

Specified by:

init in interface ProcessorService

Overrides:

init in class AbstractProcessorService

config - service configuration as specified in processor.yaml

spec - passed by the user when creating the processor (for instance via the REST API)

setParameterListener

public void setParameterListener(ParameterListener parameterListener)

Description copied from interface: ParameterProvider

Send parameters to this listener. Normally is the channel.parameterRequestManager but something different may be used for unit tests or special applications (PacketViewer)

Specified by:

setParameterListener in interface ParameterProvider

addParameterListener

public void addParameterListener(ParameterListener parameterListener)

updateParameters

public void updateParameters(List<ParameterValue> pvList)

update the list of parameters. - resolves NamedObjectId -> Parameter - sends the result to PRM

Specified by:

updateParameters in interface SoftwareParameterManager

updateParameter

public void updateParameter(Parameter p,
