Class StatusQosData

java.lang.Object
  org.xmlBlaster.util.qos.QosData
      org.xmlBlaster.util.qos.StatusQosData

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public final class StatusQosData
extends QosData
implements java.io.Serializable, java.lang.Cloneable

Data container handling of status returned by subscribe(), unSubscribe(), erase() and ping().

This data holder is accessible through decorators, each of them allowing a specialized view on the data:

• SubscribeReturnQos Returned QoS of a subscribe() invocation (Client side)
• UnSubscribeReturnQos Returned QoS of a unSubscribe() invocation (Client side)
• EraseReturnQos Returned QoS of an erase() invocation (Client side)

For the xml representation see StatusQosSaxFactory.

Constructor Detail

StatusQosData

public StatusQosData(Global glob,
                     MethodName methodName)

Constructs the specialized quality of service object for status informations, e.g. for a return of a subscribe() call

The state defaults to Constants.STATE_OK

Parameters:

The - factory which knows how to serialize and parse me

StatusQosData

public StatusQosData(Global glob,
                     I_StatusQosFactory factory,
                     MethodName methodName)

Constructs the specialized quality of service object for status informations. E.g. for a return of a subscribe() call

Parameters:

The - factory which knows how to serialize and parse me

StatusQosData

public StatusQosData(Global glob,
                     I_StatusQosFactory factory,
                     java.lang.String serialData,
                     MethodName methodName)

Constructs the specialized quality of service object for a publish() call. For internal use only, this message is sent from the persistence layer

Parameters:

the - XML based ASCII string

true -

Method Detail

setSubscriptionId

public void setSubscriptionId(java.lang.String subscriptionId)

If Pub/Sub style update: contains the subscribe ID which caused this update

Parameters:

subscriptionId - null if PtP message

getSubscriptionId

public java.lang.String getSubscriptionId()

If Pub/Sub style update: contains the subscribe ID which caused this update

Returns:

subscribeId or null if PtP message

getKeyOid

public java.lang.String getKeyOid()

Access key oid.

Returns:

The unique identifier of a message

setKeyOid

public void setKeyOid(java.lang.String oid)

toJXPath

public java.util.Hashtable toJXPath()

Dump the QoS to a flattened JXPath representation.

This is experimental code for the simple Applet client

   /qos/state/@id             -> getState()
   /qos/state/@info           -> getStateInfo()
   /qos/rcvTimestamp/@nanos   -> getRcvTimestamp()
   /qos/rcvTimestamp/text()   -> getRcvTime()
   /qos/methodName/text()     -> getMethod()
   /qos/key/@oid              -> getKeyOid()
   /qos/subscribe/@id         -> getSubscriptionId()
 

Currently only an UpdateQos dump is supported
