Public Instance methods

to_json(state = nil, depth = 0, *)

Returns a JSON string containing a JSON array, that is unparsed from this Array 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.
