com.archimed.dicom.network.Association

public class Association
extends java.lang.Object

replaced by AssociationIO.

This class contains methods to build up and break down an association between two DICOM application entities and to send DICOM commands and data sets once an association is established.

Note: This class is replaced by the AssociationIO class and is maintained for backwards compatibility. New implementations should make use of the AssocationIO class.

Since:

1.00
