Instance Method Details

#each(&out_block) ⇒ Object

Iterate the output tokens. The block will receive JSON delimeters individually as strings, and string values as quoted strings. If called without a block, returns an enumerator.

Example:

json.each {|token| puts token}

def each(&out_block)
  e = Enumerator.new {|yielder|
    Collector.new(yielder).collect &@body_block
  }

  out_block ? e.each(&out_block) : e
end

#to_s ⇒ Object

Produce a compact string of the JSON. The entire string is produced at once; this is not suitable for very large JSON output.
