public String bucket()
public String ifMatch()
Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).
public Instant ifModifiedSince()
Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).
public String ifNoneMatch()
Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).
public Instant ifUnmodifiedSince()
Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).
public String key()
public String range()
Downloads the specified range bytes of an object. For more information about the HTTP Range header, go to http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.
public String versionId()
VersionId used to reference a specific version of the object.
public String sseCustomerAlgorithm()
Specifies the algorithm to use to when encrypting the object (e.g., AES256).
public String sseCustomerKey()
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
public String sseCustomerKeyMD5()
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure the encryption key was transmitted without error.
public RequestPayer requestPayer()
If the service returns an enum value that is not available in the current SDK version, requestPayer
will
return RequestPayer.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available from
requestPayerAsString()
.
RequestPayer
public String requestPayerAsString()
If the service returns an enum value that is not available in the current SDK version, requestPayer
will
return RequestPayer.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available from
requestPayerAsString()
.
RequestPayer
public Integer partNumber()
Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
