Method Detail

bucket

public String bucket()

Returns:

ifMatch

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).

Returns:

Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).

ifModifiedSince

public Date ifModifiedSince()

Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).

Returns:

Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).

ifNoneMatch

public String ifNoneMatch()

Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).

Returns:

Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).

ifUnmodifiedSince

public Date ifUnmodifiedSince()

Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).

Returns:

Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).

key

public String key()

Returns:

range

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.

Returns:

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.

versionId

public String versionId()

VersionId used to reference a specific version of the object.

Returns:

VersionId used to reference a specific version of the object.

sseCustomerAlgorithm

public String sseCustomerAlgorithm()

Specifies the algorithm to use to when encrypting the object (e.g., AES256).

Returns:

Specifies the algorithm to use to when encrypting the object (e.g., AES256).

sseCustomerKey

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.

Returns:

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.

sseCustomerKeyMD5

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.

Returns:

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.

requestPayer

public String requestPayer()

Returns:

RequestPayer

partNumber

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.

Returns:
