Overview

The channels this deployment speaks, by id. A Registry like tools and workflows — same plugin bookkeeping, so deregister_plugin rolls a half-registered plugin back exactly as it does for a tool.

The id is the URL segment (/channels/relay/events), which is why lookup here is a find and not a resolve: an unknown segment is a 404, not an exception the transport has to rescue.

Instance Method Details

#deliverable?(id) ⇒ Boolean

Does this channel deliver out of band (Shape B)? A Shape A channel answers on the request's own stream and has no deliver, so nothing is ever written to the outbox for it. Duck-typed, like every other seam in the engine.

Returns:

  • (Boolean)

def deliverable?(id)
  channel = find(id)
  !channel.nil? && channel.respond_to?(:deliver)
end

#find(id) ⇒ Object

-> the channel instance | nil (unknown id). A blank id never matches.
