com.pixelmed.network.CompositeResponseHandler
- Direct Known Subclasses:
MoveSOPClassSCU.CMoveResponseHandler
,StorageSOPClassSCU.CStoreResponseHandler
,VerificationSOPClassSCU.CEchoResponseHandler
This abstract class provides a mechanism to process each PDU of a composite response as it is received, such as for evaluating the status of the response for success.
Typically a private sub-class would be declared and instantiated with overriding methods to evaluate the success or failure of a storage or query or retrieve response.
