Properties

acceptRanges → String?
Indicates that a range of bytes was specified.
final
archiveStatus → ArchiveStatus?
The archive state of the head object.
final
bucketKeyEnabled → bool?
Indicates whether the object uses an S3 Bucket Key for server-side encryption with AWS KMS (SSE-KMS).
final
cacheControl → String?
Specifies caching behavior along the request/reply chain.
final
contentDisposition → String?
Specifies presentational information for the object.
final
contentEncoding → String?
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
final
contentLanguage → String?
The language the content is in.
final
contentLength → int?
Size of the body in bytes.
final
contentType → String?
A standard MIME type describing the format of the object data.
final
deleteMarker → bool?
Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.
final
eTag → String?
An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL.
final
expiration → String?
If the object expiration is configured (see PUT Bucket lifecycle), the response includes this header. It includes the expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL encoded.
final
expires → DateTime?
The date and time at which the object is no longer cacheable.
final
hashCode → int
The hash code for this object.
no setterinherited
lastModified → DateTime?
Last modified date of the object
final
metadata → Map<String, String>?
A map of metadata to store with the object in S3.
final
missingMeta → int?
This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.
final
objectLockLegalHoldStatus → ObjectLockLegalHoldStatus?
Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock.
final
objectLockMode → ObjectLockMode?
The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock.
final
objectLockRetainUntilDate → DateTime?
The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.
final
partsCount → int?
The count of parts this object has.
final
replicationStatus → ReplicationStatus?
Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.
final
requestCharged → RequestCharged?
final
restore → String?
If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
serverSideEncryption → ServerSideEncryption?
If the object is stored using server-side encryption either with an AWS KMS customer master key (CMK) or an Amazon S3-managed encryption key, the response includes this header with the value of the server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
final
sSECustomerAlgorithm → String?
If server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.
final
sSECustomerKeyMD5 → String?
If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.
final
sSEKMSKeyId → String?
If present, specifies the ID of the AWS Key Management Service (AWS KMS) symmetric customer managed customer master key (CMK) that was used for the object.
final
storageClass → StorageClass?
Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.
final
versionId → String?
Version of the object.
final
websiteRedirectLocation → String?
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
final
