        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.

Method Detail

verify

public void verify(java.lang.String strcallingAETitle,
          java.lang.String strCalledAETitle)
            throws java.io.IOException

This method establish association by Default association. Creates default C-Echo RQ. Sends the CEcho request to given AE title ,release the association and close the connection.

Parameters:

strcallingAETitle - calling AE title for this service provider

strCalledAETitle - called AE title for verification

Throws:

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

verify

public void verify(CEchoRQ objCEchoRQ,
          java.lang.String strcallingAETitle,
          java.lang.String strCalledAETitle)
            throws java.io.IOException

This method establish association by Default association using given AE Titles. Sends the CEcho request , release the association and close the connection.

Parameters:

strcallingAETitle - calling AE title for this service provider

strCalledAETitle - called AE title for verification

objCEchoRQ - CEcho request i.e. to be sent to SCP.

Throws:

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

verify

public void verify(AssociateRQ objAssociateRQ,
          CEchoRQ objCEchoRQ)
            throws java.io.IOException

Sends the C-Echo request to the SCP. While sending the request, 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 C-ECHO SCU.

Parameters:

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

objCEchoRQ - CEcho request i.e. to be sent to SCP.

Throws:

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