Overview

:stopdoc: This class is used by Raindrops::Middleware to proxy application response bodies. There should be no need to use it directly.

#initialize(body, stats) ⇒ Proxy

Returns a new instance of Proxy.

def initialize(body, stats)
  @body, @stats = body, stats
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args, &block) ⇒ Object

Avoid breaking users of non-standard extensions (e.g. #body) Rack::BodyProxy does the same.

#close ⇒ Object

the Rack server should call this after #each (usually ensure-d)

def close
  @stats.decr_writing
  @body.close if @body.respond_to?(:close)
end

#each ⇒ Object

yield to the Rack server here for writing

def each
  @body.each { |x| yield x }
end

#respond_to?(m, include_all = false) ⇒ Boolean

Rack servers use respond_to? to check for the presence of close and to_path methods.

Returns:

  • (Boolean)

def respond_to?(m, include_all = false)
  m = m.to_sym
  :close == m || @body.respond_to?(m, include_all)
end

#to_path ⇒ Object

Some Rack servers can optimize response processing if it responds to to_path via the sendfile(2) system call, we proxy to_path to the underlying body if possible.
