to_json(state = nil, depth = 0)

Returns a JSON string containing a JSON object, that is unparsed from this Hash instance. state is a JSON::State object, that can also be used to configure the produced JSON string output further. depth is used to find out nesting depth, to indent accordingly.

    state = JSON::State.from_state(state)
    json_check_circular(state) { json_transform(state, depth) }
  end
to_openobject()

Convert a Hash into an OpenObject.
