@Provides
S3Object newS3Object()
```
    Creates a default implementation of S3Object
  - getObject
```
S3Object getObject(String bucketName,
                 String key,
                 GetOptions... options)
```
    Retrieves the S3Object associated with the Key or KeyNotFoundException if not available;
    To use GET, you must have READ access to the object. If READ access is granted to the anonymous user, you can request the object without an authorization header.
    This command allows you to specify GetObjectOptions to control delivery of content.
    Note
    If you specify any of the below options, you will receive partial content:
    - GetObjectOptions#range
    - GetObjectOptions#startAt
    - GetObjectOptions#tail
    Parameters:
    bucketName - namespace of the object you are retrieving
    key - unique key in the s3Bucket identifying the object
    
    Returns:
    Future reference to a fully populated S3Object including data stored in S3 or S3Object#NOT_FOUND if not present.
    
    Throws:
    
    HttpResponseException - if the conditions requested set were not satisfied by the object on the server.

ObjectMetadata headObject(String bucketName,
                        String key)
```
    Retrieves the metadata of the object associated with the key or org.jclouds.s3.domain.internal.BucketListObjectMetadata#NOT_FOUND if not available.
    The HEAD operation is used to retrieve information about a specific object or object size, without actually fetching the object itself. This is useful if you're only interested in the object metadata, and don't want to waste bandwidth on the object data.
    
    Parameters:
    bucketName - namespace of the metadata you are retrieving
    key - unique key in the s3Bucket identifying the object
    
    Returns:
    metadata associated with the key or org.jclouds.s3.domain.internal.BucketListObjectMetadata#NOT_FOUND if not present;

                String key)
```
    Removes the object and metadata associated with the key.
    The DELETE request operation removes the specified object from Amazon S3. Once deleted, there is no method to restore or undelete an object.
    
    Parameters:
    bucketName - namespace of the object you are deleting
    key - unique key in the s3Bucket identifying the object
    
    Throws:

    This method will store the object with the default private This returns a byte[] of the eTag hash of what Amazon S3 received
    
    Parameters:
    bucketName - namespace of the object you are storing
    object - contains the data and metadata to create or overwrite
    options - options for creating the object
    
    Returns:
    ETag of the content uploaded

```
    Create and name your own bucket in which to store your objects.
    you can use PutBucketOptions to create the bucket in EU.
    The PUT request operation with a bucket URI creates a new bucket. Depending on your latency and legal requirements, you can specify a location constraint that will affect where your data physically resides. You can currently specify a Europe (EU) location constraint via PutBucketOptions.
    
    Parameters:
    options - for creating your bucket
    
    Returns:
    true, if the bucket was created or false, if the container was already present

  - deleteBucketIfEmpty
```
boolean deleteBucketIfEmpty(String bucketName)
```
    Deletes the bucket, if it is empty.
    The DELETE request operation deletes the bucket named in the URI. All objects in the bucket must be deleted before the bucket itself can be deleted.
    Only the owner of a bucket can delete it, regardless of the bucket's access control policy.
    
    Parameters:
    bucketName - what to delete
    
    Returns:
    false, if the bucket was not empty and therefore not deleted

    Retrieve a S3Bucket listing. A GET request operation using a bucket URI lists information about the objects in the bucket. You can use ListBucketOptions to control the amount of S3Objects to return.
    To list the keys of a bucket, you must have READ access to the bucket.
    
    Parameters:
    bucketName - namespace of the objects you wish to list
    
    Returns:
    Future reference to a fully populated S3Bucket including metadata of the S3Objects it contains or BoundedList#NOT_FOUND if not present.

                        String destinationObject,
                        CopyObjectOptions... options)
```
    Copies one object to another bucket, retaining UserMetadata from the source. The destination will have a private acl. The copy operation creates a copy of an object that is already stored in Amazon S3.
    When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request.
    
    Returns:
    metadata populated with lastModified and eTag of the new object
    
    Throws:
    
    HttpResponseException - if the conditions requested set are not satisfied by the object on the server.
