Overview

WavefrontCli::Base looks for a class WavefrontOutput::Format where ‘Format’ is something like ‘Json’, or ‘Yaml’. If it finds that class it creates a new instance, passing through the response object (@resp) and options hash (@options), then calls the #run method.

All those classes are an extension of this one. Some, like Json or Yaml, are generic, and dump a straight translation of the response object. Others, like Hcl or Wavefront, have subclasses which deal with the output of specific commands.
