is equivalent to |

472
|
|
|
|
|
|
|
|
473
|
|
|
|
|
|
|
If the parameters are passed as a hashref, the keys are the names of the parameters, and they will |
474
|
|
|
|
|
|
|
appear in the swagger document following their alphabetical order. |
475
|
|
|
|
|
|
|
|
476
|
|
|
|
|
|
|
If the parameters are passed as an arrayref, they will appear in the document in the order |
477
|
|
|
|
|
|
|
in which they are passed. Additionally, each parameter can be given as a hashref, or can be a |
478
|
|
|
|
|
|
|
C<< name => arguments >> pair. |
479
|
|
|
|
|
|
|
|
480
|
|
|
|
|
|
|
In both format, for the key/value pairs, a string value is considered to be the |
481
|
|

C<description> of the parameter. |
482
|
|
|
|
|
|
|
|
483
|
|

Finally, if not specified explicitly, the C<in> argument of a parameter defaults to C<query>, |
484
|
|
|
|
|
|
|
and its type to C<string>. |

Accepts an optional C<skip> parameter that takes an arrayref of |

routes that shouldn't be added to the Swagger document. The routes |
570

can be specified as-is, or via regular expressions. If no skip list is given, defaults to |

The information of a route won't be altered if it's |

If a route has path parameters, they will be automatically |

580
|
|
|
|
|

Note that routes defined after C<swagger_auto_discover> has been called won't |
594
|
|
|
|
|
|
|
be added to the Swagger document. Typically, you'll want C<swagger_auto_discover> |
595
|
|
|
|
|
|
|
to be called at the very end of your module. Alternatively, C<swagger_auto_discover> |
596
|
|
|
|
|
|
|
can be called more than once safely -- which can be useful if an application creates |
597

|
routes dynamically. |
