Instance Method Details

#proxy(peer) ⇒ Object

Create a new proxy which maps the object of peer represented by this communication intermediate.

# File 'lib/roby/distributed/proxy.rb', line 314

def proxy(peer); peer.connection_space.plan end

#remote_siblings ⇒ Object

The set of remote siblings for that object. This is used to avoid creating proxies when not needed. See PlanObject::DRoby#remote_siblings.

# File 'lib/roby/distributed/proxy.rb', line 321

def remote_siblings; @remote_siblings ||= Hash[peer, id] end

#sibling_on(peer) ⇒ Object

If peer is the plan’s owner, returns #id. Otherwise, raises RemotePeerMismatch. This is used to avoid creating proxies when not needed. See BasicObject::DRoby#sibling_on.
