Class ReceivedDataHandler

  • Direct Known Subclasses:
    CompositeResponseHandler
    public abstract class ReceivedDataHandler
extends java.lang.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.
