A container for responses available from the current controller for requests for different mime-types sent to a particular action.
The public controller methods respond_with and respond_to may be called with a block that is used to define responses to different mime-types, e.g. for respond_to :
respond_to do |format| format.html format.xml { render xml: @people } end
In this usage, the argument passed to the block (format above) is an instance of the ActionController::MimeResponds::Collector class. This object serves as a container in which available responses can be stored by calling any of the dynamically generated, mime-type-specific methods such as html, xml etc on the Collector. Each response is represented by a corresponding block if present.
A subsequent call to negotiate_format(request) will enable the Collector to determine which specific mime-type it should respond with for the current request, with this response then being accessible by calling response.
