/**
 * <p>Retrieves the <code>PublicAccessBlock</code> configuration for an Amazon S3 bucket. To use
 *          this operation, you must have the <code>s3:GetBucketPublicAccessBlock</code> permission.
 *          For more information about Amazon S3 permissions, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/using-with-s3-actions.html">Specifying Permissions in a
 *          Policy</a>.</p>
 *
 *          <important>
 *             <p>When Amazon S3 evaluates the <code>PublicAccessBlock</code> configuration for a bucket or
 *             an object, it checks the <code>PublicAccessBlock</code> configuration for both the
 *             bucket (or the bucket that contains the object) and the bucket owner's account. If the
 *                <code>PublicAccessBlock</code> settings are different between the bucket and the
 *             account, Amazon S3 uses the most restrictive combination of the bucket-level and
 *             account-level settings.</p>
 *          </important>
 *
 *          <p>For more information about when Amazon S3 considers a bucket or an object public, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/access-control-block-public-access.html#access-control-block-public-access-policy-status">The Meaning of "Public"</a>.</p>
