def cp new_uri
  IMW::Tools::Transferer.new(:cp, self, new_uri).transfer!
end

#delete(headers = {}) {|RestClient::Response| ... } ⇒ RestClient::Response

Send a DELETE request to this resource’s URI.

If the response doesn’t have HTTP code 2xx, a RestClient error will be raised.

If a block is given then the response will be passed to the block, even in case of a non-2xx code.

See the documentation for RestClient for more information.

Parameters:

  • headers (Hash) (defaults to: {}) —

    the headers to include in the request

Yields:

  • (RestClient::Response) —

    the response from the server

Returns:

  • (RestClient::Response) —

    the response from the server

Raises:

  • (RestClient::NotModified, RestClient::Unauthorized, RestClient::ResourceNotFound, RestClient::RequestFailed) —

    error from RestClient on non-2xx response codes
