In this case, `item_id` is declared to be an `int`.

This will give you editor support inside of your function, with error checks, completion, etc.

### Custom Content Extractor

```java
public class CustomExtractor extends AbstractExtractor {
    @Override

Then, you try with the old programmer's friend, editor autocompletion.

You type the first parameter of the function, `first_name`, then a dot (`.`) and then hit `Ctrl+Space` to trigger the completion.

But, sadly, you get nothing useful:

### Add types { #add-types }

Let's modify a single line from the previous version.

以前は不可能だと考えていたコードでさえ補完されます。例えば、リクエストからのJSONボディ（ネストされている可能性がある）内の `price`キーです。

along with the applicable date(defaults to time of initiating the reset). All objects created prior to this date are eligible for re-replication if existing object replication is enabled for the replication rule the object satisfies. At the time of completion of replication, `x-minio-internal-replication-reset-arn:<arn>` is set in the metadata with the timestamp of replication and ResetID. For saving iops, the objects which are re-replicated are not first set to `PENDING` state.

This is a slower...
