    #jsonify(value)   (private)
  



  

    

Convert an object into a “JSON-ready” representation composed of primitives like ::Hash, ::Array, ::String, ::Symbol, ::Numeric, and true+/false/+nil. Recursively calls #as_json to the object to recursively build a fully JSON-ready object.



This allows developers to implement #as_json without having to worry about what base types of objects they are allowed to return or having to remember to call #as_json recursively.



Note: the #options hash passed to object.to_json is only passed to object.as_json, not any of this method’s recursive #as_json calls.
