## Example

```ts

// The values are placeholders you should change.
import { aws_iotsitewise as iotsitewise } from 'aws-cdk-lib';
const s3AccessPointSourceProperty: iotsitewise.CfnTask.S3AccessPointSourceProperty = {
  accessPointArn: 'accessPointArn',

  // the properties below are optional
  prefix: 'prefix',
};
```

## Properties

- `accessPointArn`: string (required) — The Amazon Resource Name (ARN) of the Amazon S3 access point.

  The mount reads objects from the bucket associated with this access point. Access is governed by the access point policy and the task execution role's IAM permissions.

- `prefix`: string — An object key name prefix.

  If specified, the mount includes only objects whose keys begin with this prefix. To include all objects at the access point, omit this field.
