## Callback'i dokümante etmek { #documenting-the-callback }

Callback'in gerçek kodu, büyük ölçüde sizin API uygulamanıza bağlıdır.

Ve bir uygulamadan diğerine oldukça değişebilir.

Sadece bir-iki satır kod bile olabilir, örneğin:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

  interface ItemReporter {
    String reportItem(Item<?> item);
  }

  /**
   * A word about using {@link Equivalence}, which automatically checks for {@code null} and
   * identical inputs: This sounds like it ought to be a problem here, since the goals of this class
   * include testing that {@code equals()} is reflexive and is tolerant of {@code null}. However,

import org.jspecify.annotations.Nullable;

final class TestingCacheLoaders {

  /**
   * Returns a {@link CacheLoader} that implements a naive {@link CacheLoader#loadAll}, delegating

   * @return the value that was previously associated with the key, or {@code null} if there was no
   *     previous entry. (If the bimap contains null values, then {@code forcePut}, like {@code
   *     put}, returns {@code null} both if the key is absent and if it is present with a null
   *     value.)

  @CanIgnoreReturnValue

   * useful to call from vanilla JavaScript because it returns an instance of Class, which can't be
   * converted to a standard JavaScript type. (Contrast to something like String or boolean.) Since
   * we're not calling it from JavaScript, we suppress the warning.

// objSweeper determines if a transitioned object needs to be removed from the remote tier.
// A typical usage would be like,
// os := newObjSweeper(bucket, object)
// // Perform a ObjectLayer.GetObjectInfo to fetch object version information
// goiOpts := os.GetOpts()
// gerr := objAPI.GetObjectInfo(ctx, bucket, object, goiOpts)

### TODO

In subsequent releases we are planning to extend this to provide things like

- Reload() of MinIO server arguments without fully restarting the process.

- Expanding 1 node at a time by automating the process of creating a new pool

// [io.ByteScanner], and [io.RuneScanner] interfaces by reading from
// a byte slice.
// Unlike a [Buffer], a Reader is read-only and supports seeking.
// The zero value for Reader operates like a Reader of an empty slice.
type Reader struct {
	s        []byte
	i        int64 // current reading index
	prevRune int   // index of previous rune; or < 0
}
