All Implemented Interfaces:

IMessageListener

public class CGetSCU
extends SCU

The C-GET service is used by a DIMSE-service-user to match and retrieve a set of Attributes against the Attributes of a set of composite SOP Instances maintained by a peer DIMSE-service-user. This class implements functioning of CGet Service User.

Constructor Detail

CGetSCU

public CGetSCU(java.lang.String strIP,
       int port)
        throws java.io.IOException

The IP and port to which user connects.

Parameters:

strIP - String value of IP to which user connects.

port - Port to which user connects.

Throws:

java.io.IOException - Signals IO Exception if IO operation fails.

CGetSCU

public CGetSCU(java.net.InetSocketAddress addr)
        throws java.io.IOException

The InetAddress and port to which user connects.

Parameters:

addr - InetAddress to which user connects.

Throws:

java.io.IOException - Signals IO Exception if IO operation fails.

CGetSCU

public CGetSCU(SCUSession objSCUSession)

Parameterized constructor initializes CGet SCP with given session and registers itself to SCUSession to work as ResponseListener.

Parameters:

objSCUSession - instance of SCU Session.

Method Detail

getDestinationPath

public java.lang.String getDestinationPath()

Sets the destination path to store the file.

Returns:

String value of Storage Destination Path

setDestinationPath

public void setDestinationPath(java.lang.String strStorageDestPath)

Retrieves the destination path to store the file.

Parameters:

strStorageDestPath - the strStorageDestPath to set

getDataSink

public IDataSink getDataSink()

Retrieves the DataSink

Returns:

the instance of DataSink

setDataSink

public void setDataSink(IDataSink objIDataSink)

Sets the Data Sink.

Parameters:

objIDataSink - object of Data Sink.

sendRequests

public void sendRequests(ISingleCollection<CGetRQ> objRQCollection)
                  throws java.io.IOException

This method sends multiple CStore RQ.

Parameters:

objRQCollection - Collection of CStoreRQ i.e. to be send.

Throws:

java.io.IOException - Signals that an I/O exception has occurred.

send

public void send(java.lang.String strCalledAETitle,
        java.lang.String strCallingAETitle,
        java.lang.String strAffectedSOPClassUID,
        ISingleCollection<IDataSet> objDataSetCollection)
          throws java.io.IOException

This method creates association request according to the DataSet collection provided by the user and the Default association. Then it will perform the C-Move operation on the data set provided by the user, release the association and close the connection.

Parameters:

strcallingAETitle - calling AE title for this service provider.

strCalledAETitle - called AE title for user .

strAffectedSOPClassUID - String value of Affected SOP Class UID.

objDataSetCollection - Collection of Data Set containing identifier on which C-Move operation has to be performed.

Throws:

java.io.IOException - Signals IOException of IO operation fails.

send

public void send(java.lang.String strAffectedSOPClassUID,
        AssociateRQ objAssociateRQ,
        ISingleCollection<IDataSet> objDataSetCollection)
          throws java.io.IOException

Sends the available datasets to the SCP. While sending the datasets, if the connection is not made to the destination SCP, then the SCU first creates the connection. If the association is not created with the destination SCP, then the SCU first establishes the association and then sends the datasets. Note: The SCU will not close the connection, if already created connection is given to the SCU in the form of SCUSession. The SCU will neither release the association nor close the connection, if the association is already established with the destination SCP through SCUSession. User has to explicitly release the association and close the connection after completion of send process of CSTORE SCU.

Parameters:

strAffectedSOPClassUID - String value of Affected SOP Class UID.

objAssociateRQ - The association request i.e. to be sent to SCP.

objDataSetCollection - Collection of Data Set on which C-Store operation has to be performed.

Throws:

java.io.IOException - Signals IOException if IO operation fails.

receiveMessage

public void receiveMessage(ServiceMessageEvent objServiceMessageEvent)
                    throws java.io.IOException

It processes the received Dicom Message ,retrieved from event generated, according to it's Command Type.

Specified by:

receiveMessage in interface IMessageListener

Overrides:

receiveMessage in class SCU

Parameters:

objServiceMessageEvent - instance of ServiceMessageEvent.

Throws:

sendMessage

public boolean sendMessage(DicomMessage objDicomMessage)
                    throws java.io.IOException

Sends the DicomMessage to SCUSession for further processing and waits untill final CGetRSP is arrived.

Specified by:

sendMessage in interface IMessageListener

Specified by:

sendMessage in class SCU

Parameters:

objDicomMessage - instance of DicomMessage.

Returns:

true, if message send.

Throws:

java.io.IOException - Signals that an I/O exception has occurred.
