Defined in:
lib/farcall/endpoint.rb

Overview

Interface to the remote provider via Farcall protocols. Works the same as the normal, local object, but slower. This interface is returned by Endpoint#remote. The Interface transparently creates methods as you call them to speed up subsequent calls.

There is no way to check that the remote responds to some method other than call it and catch the exception.

See RemoteError for more information on passing errors.

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *arguments, **kw_arguments, &block) ⇒ Object

used internally to synthesize the proxy method.
