DESCRIPTION
This is an action role that lets your Catalyst::Action match on the content type of the incoming request.

Generally when there's a PUT or POST request, there's a request content body with a matching MIME content type. Commonly this will be one of the types used with classic HTML forms ('application/x-www-form-urlencoded' for example) but there's nothing stopping you specifying any valid content type.

For matching purposes, we match strings but the casing is insensitive.

REQUIRES
This role requires the following methods in the consuming class.

  match

  match_captures
Returns 1 if the action matches the existing request and zero if not.

METHODS
This role defines the following methods

  match

  match_captures
Around method modifier that return 1 if the request content type matches one of the allowed content types (see "http_methods") and zero otherwise.

  allowed_content_types
An array of strings that are the allowed content types for matching this action.

  can_consume
Boolean. Does the current request match content type with what this actionrole can consume?

  list_extra_info
Add the accepted content type to the debug screen.
