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.
    
    See Also:

    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.

  - getRestoreExpirationTime
```
public Date getRestoreExpirationTime()
```
    Returns the time at which an object that has been temporarily restored from Amazon Glacier will expire, and will need to be restored again in order to be accessed. Returns null if this is not a temporary copy of an object restored from Glacier.
    
    Specified by:
    
    getRestoreExpirationTime in interface ObjectRestoreResult
  - setRestoreExpirationTime
```
public void setRestoreExpirationTime(Date restoreExpirationTime)
```

    Specified by:
    
    setRestoreExpirationTime in interface ObjectRestoreResult
    
    Parameters:
    
    restoreExpirationTime - The new restore expiration time for the object.
  - setOngoingRestore
```
public void setOngoingRestore(boolean ongoingRestore)
```
    For internal use only. Sets the boolean value which indicates whether there is ongoing restore request. Not intended to be called by external code.
    
    Specified by:
    
    setOngoingRestore in interface ObjectRestoreResult
  - getOngoingRestore
```
public Boolean getOngoingRestore()
```
    Returns the boolean value which indicates whether there is ongoing restore request.
    
    Specified by:
    
    getOngoingRestore in interface ObjectRestoreResult
  - setHttpExpiresDate
```
public void setHttpExpiresDate(Date httpExpiresDate)
```
    Set the date when the object is no longer cacheable.
  - getHttpExpiresDate
```
public Date getHttpExpiresDate()
```
    Returns the date when the object is no longer cacheable.
  - getStorageClass
```
public String getStorageClass()
```
    Returns:
    
    The storage class of the object. Returns null if the object is in STANDARD storage. See StorageClass for possible values
  - getUserMetaDataOf
```
public String getUserMetaDataOf(String key)
```
    Returns the value of the specified user meta datum.
  - clone
```
public ObjectMetadata clone()
```
    Returns a clone of this ObjectMetadata. Note the clone of the internal metadata is limited to a shallow copy due to the unlimited type of value in the map. Other fields can be regarded as deep clone.
    
    Overrides:
    
    clone in class Object
  - getSSEAwsKmsKeyId
```
public String getSSEAwsKmsKeyId()
```
    Returns the AWS Key Management System key id used for Server Side Encryption of the Amazon S3 object.
  - isRequesterCharged
```
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.
    
    If the request specifies a range or part number, then response returns the Content-Range range header. Otherwise, the response does not return Content-Range header.
    
    Returns:
    
    Returns content range if the object is requested with specific range or part number, null otherwise.
  - getReplicationStatus
```
public String getReplicationStatus()
```
    Returns:
