public abstract class ChannelAccessSubscriptionMessage extends ChannelAccessMessage
Base class for CA_PROTO_EVENT_ADD
messages.
This message type is used by clients to request an event subscription and by
servers for subscription events or to confirm the cancellation of a request
subscription. As the format of the two server variants is different, there
are two classes for them. ChannelAccessSubscriptionServerMessage
is
used to send a subscription event and
ChannelAccessCancelSubscriptionServerMessage
is used to confirm a
cancellation request. The latter can be identified by having a payload size
of zero.
