Defined in:
lib/chef/sugar/node.rb

Provide a nice DSL for defining attributes. method_missing is called on all the attribute names. For more information on how to use the DSL, see the class-level documentation.

  • to prevent accidential method chaining if the block isn’t closed

  • If no argument is passed in, method becomes an attribute accessor
