#map(opts) ⇒ Object

Rudimentary routing support for channels to controllers.

Parameters:

  • opts —

    a Hash of mappings either string keys (channel globs) mapping to controller constants eg:

    '/widgets/**' => WidgetsController

    or you can set the behaviour for unknown channels:

    :default => :block

    :default can be set to :allow, :drop or :block. if :drop is chosen then messages to unknown channels will be silently dropped, whereas if you choose :block then the message will be returned with the error “Permission denied.”
