pure virtual

Parameters

status

Completion status.

Implemented in epics::pvAccess::ServerChannelFindRequesterImpl.

virtual std::tr1::shared_ptr<const PeerInfo> epics::pvAccess::ChannelFindRequester::getPeerInfo ( )

inlinevirtual

Return information on requesting peer if applicable.

A server-type ChannelProvider will use this method to discover if a remote client has provided credentials which may be used in access control decisions.

The returned PeerInfo is only required to have valid values for: peer, transport, and transportVersion. PeerInfo::authority may be empty if authentication has not yet occured (UDP search).

Default implementation returns NULL.

isConnected()==true and getPeerInfo()==NULL when the ChannelProvider does not provide information about the peer. This should be treated as an unauthenticated, anonymous, peer.

The returned instance must not change, and a different instance should be returned if/when peer information changes (eg. after reconnect).

May return !NULL when !isConnected(). getPeerInfo() must be called before testing isConnected() in situations where connection state is being polled.

Reimplemented in epics::pvAccess::ServerChannelFindRequesterImpl.
