Class DataStatus

java.lang.Object
  org.lsst.ccs.bus.BusMessage
      org.lsst.ccs.bus.Status
          org.lsst.ccs.bus.DataStatus

All Implemented Interfaces:

Serializable, BusPayload

Direct Known Subclasses:

TrendingStatus

public class DataStatus
extends Status

Status with additional information.

This class can used instead of subclassing Status: if the receiver does not have the needed classes in its classPath the code won't crash .

DataStatus

public DataStatus(Serializable serializable)

any Object including null values.

Parameters:

serializable -

DataStatus

public DataStatus(Class clazz,
                  Serializable serializable)

to be mostly used when primitive types are to be used. (the real type such as Integer.TYPE is kept)

Parameters:

clazz -

serializable -

Method Detail

isOfWellKnownType

public boolean isOfWellKnownType()

is the content of a "Well known type" as defined in ObjectNType. Developers of subclasses should override this method.

Returns:

isOfPrimitiveType

public boolean isOfPrimitiveType()

is the content to be considered of a primitive type? Developers of subclasses should override this method.

Returns:

getDataClassName

public String getDataClassName()

what is the class of the contained data? Developers of subclasses should override this method.

Beware: having the corresponding class in the ClassPath does not guarantee that the object will be deserialized properly (depends on class version)

Returns:

getData

public Object getData()
               throws ClassNotFoundException

gets the data content but throws an Excepton if the object cannot be deserialized

Returns:

Throws:

ClassNotFoundException

contentString

protected String contentString()

toString

public String toString()

Overrides:

toString in class Status
