Class ReceivedDataHandler

java.lang.Object
  com.pixelmed.network.ReceivedDataHandler

Direct Known Subclasses:

CompositeResponseHandler

public abstract class ReceivedDataHandler
extends Object

This abstract class provides a mechanism to process each PDU as it is received on an association.

Typically a private sub-class would be declared and instantiated overriding the sendPDataIndication() method.

abstract void	sendPDataIndication(PDataPDU pdata, Association association) The code handling the reception of data on an Association calls this method to indicate that a PDU has been received (a P-DATA-INDICATION).

dumpPDVList

protected void dumpPDVList(LinkedList pdvList)

Dump a list of the Presentation Data Values supplied to standard error

sendPDataIndication

public abstract void sendPDataIndication(PDataPDU pdata,
                                         Association association)
                                  throws DicomNetworkException,
                                         DicomException,
                                         IOException

The code handling the reception of data on an Association calls this method to indicate that a PDU has been received (a P-DATA-INDICATION).

Parameters:

pdata - the PDU that was received

association - the association on which the PDU was received

Throws:

IOException

DicomException

DicomNetworkException

isDone

public boolean isDone()

Are we finished ?

Returns:

true when no more PDUs are expected

isToBeReleased

public boolean isToBeReleased()

Are we to release the association once done ?

Returns:

true when association is to be released once done

setDone

public void setDone(boolean done)

The code handling the reception of data on an Association calls this method to indicate that no more PDUs are expected.

Parameters:

done - to be set to true when no more PDUs are expected, usually when the last fragment of the data (or command, if no data) is seen

setRelease

public void setRelease(boolean release)

The code handling the reception of data on an Association calls this method to indicate that the association is to be released once done.

Parameters:

release - to be set to true when the assoication is to be released once done
