Instance Method Details

def _each_from_json(filename, options={})
  _each_raw_line(filename, options) do |line|
    hsh = MultiJson.load(line)
    yield receive(hsh)
  end
end

#load_json(*args) ⇒ Object

With a block, calls block on each object in turn (and returns nil)

With no block, accumulates all the instances into the array it returns. As opposed to the with-a-block case, the memory footprint of this increases as the filesize does, so use caution with large files.

Returns:

  • with a block, returns nil; with no block, an array of this class' instances
