Instance Method Details

#freeze ⇒ Object

Convert app blocks into apps by calling them, in order to force autoloads and to speed up subsequent calls. Freeze the multi_run apps so that there can be no thread safety issues at runtime.

  opts[:multi_run_apps]
end

#run(prefix, app = nil, &block) ⇒ Object

Add a rack application to dispatch to for the given prefix when r.multi_run is called. If a block is given, it is called every time there is a request for the route to get the app to call. If neither a block or an app is provided, any stored route for the prefix is removed. It is an error to provide both an app and block in the same call.
