Instance Method Details

#authorize ⇒ Object

Authorize a dispatch plan item if it contains authorization entries under it. A dispatch plan item can be authorized by source hub, or source and destination hub. Hence the status can be ‘SOURCE_AUTHORIZED`, `AUTHORIZED`, or `UNAUTHORIZED` (default). This method sets those authorization values without any other interference by looking at available data and therefore no parameters are required.

Raises:

  • (StandardError)
