#supported? ⇒ Boolean

Return true if the action is supported, and false otherwise. An action may not be supported if the type is not one of the supported types, or if an non-idemponent request is issued with get instead of post, or potentionally other reasons.

As a side-effect, this sets up additional state related to the request.

Returns:

  • (Boolean)
