public Map<String,String> getUserMetadata()
```
    Gets the custom user-metadata for the associated object.
    
    Amazon S3 can store additional metadata on objects by internally representing it as HTTP headers prefixed with "x-amz-meta-". Use user-metadata to store arbitrary metadata alongside their data in Amazon S3. When setting user metadata, callers should not include the internal "x-amz-meta-" prefix; this library will handle that for them. Likewise, when callers retrieve custom user-metadata, they will not see the "x-amz-meta-" header prefix.
    
    User-metadata keys are case insensitive and will be returned as lowercase strings, even if they were originally specified with uppercase strings.
    
    Note that user-metadata for an object is limited by the HTTP request header limit. All HTTP headers included in a request (including user metadata headers and other standard HTTP headers) must be less than 8KB.
    
    Returns:
    
    The custom user metadata for the associated object.

    This field is required when uploading objects to S3, but the AWS S3 Java client will automatically set it when working directly with files. When uploading directly from a stream, set this field if possible. Otherwise the client must buffer the entire stream in order to calculate the content length before sending the data to Amazon S3.

    When uploading files, the AWS S3 Java client will attempt to determine the correct content type if one hasn't been set yet. Users are responsible for ensuring a suitable content type is set when uploading streams. If no content type is provided and cannot be determined by the filename, the default content type, "application/octet-stream", will be used.

public boolean isRequesterCharged()
```
    Description copied from interface: S3RequesterChargedResult
    
    Returns true if the user has enabled Requester Pays option when conducting this operation from Requester Pays Bucket; else false.
    If a bucket is enabled for Requester Pays, then any attempt of operation from it without Requester Pays enabled will result in a 403 error and the bucket owner will be charged for the request.
    Enabling Requester Pays disables the ability to have anonymous access to this bucket
    
    Specified by:
    
    isRequesterCharged in interface S3RequesterChargedResult
    
    Returns:
    
    true if the user has enabled Requester Pays option for conducting this operation from Requester Pays Bucket.
  - setRequesterCharged
```
public void setRequesterCharged(boolean isRequesterCharged)
```
    Description copied from interface: S3RequesterChargedResult
    
    Used for conducting this operation from a Requester Pays Bucket. If set the requester is charged for conducting the operation from the bucket.
    If a bucket is enabled for Requester Pays, then any attempt of operation from it without Requester Pays enabled will result in a 403 error and the bucket owner will be charged for the request.
    
    Specified by:
    
    setRequesterCharged in interface S3RequesterChargedResult
    
    Parameters:
    
    isRequesterCharged - Indicates requester is charged for this operation.
  - getPartCount
```
public Integer getPartCount()
```
    Returns the value of x-amz-mp-parts-count header.
    
    The x-amz-mp-parts-count header is returned in the response only when a valid partNumber is specified in the request and the object has more than 1 part.
    
    To find the part count of an object, set the partNumber to 1 in GetObjectRequest. If the object has more than 1 part then part count will be returned, otherwise null is returned.
  - getContentRange
```
public Long[] getContentRange()
```
    Returns the content range of the object if response contains the Content-Range header.
