Object class

An object.

Constructors

Object()
Object.fromJson(Map _json)

Properties

acl List<ObjectAccessControl>
Access controls on the object.
read / write
bucket String
The name of the bucket containing this object.
read / write
cacheControl String
Cache-Control directive for the object data. If omitted, and the object is accessible to all anonymous users, the default will be public, max-age=3600.
read / write
componentCount int
Number of underlying components that make up this object. Components are accumulated by compose operations.
read / write
contentDisposition String
Content-Disposition of the object data.
read / write
contentEncoding String
Content-Encoding of the object data.
read / write
contentLanguage String
Content-Language of the object data.
read / write
contentType String
Content-Type of the object data. If an object is stored without a Content-Type, it is served as application/octet-stream.
read / write
crc32c String
CRC32c checksum, as described in RFC 4960, Appendix B; encoded using base64 in big-endian byte order. For more information about using the CRC32c checksum, see Hashes and ETags: Best Practices.
read / write
customerEncryption ObjectCustomerEncryption
Metadata of customer-supplied encryption key, if the object is encrypted by such a key.
read / write
customTime DateTime
A timestamp in RFC 3339 format specified by the user for an object.
read / write
etag String
HTTP 1.1 Entity tag for the object.
read / write
eventBasedHold bool
Whether an object is under event-based hold. Event-based hold is a way to retain objects until an event occurs, which is signified by the hold's release (i.e. this value is set to false). After being released (set to false), such objects will be subject to bucket-level retention (if any). One sample use case of this flag is for banks to hold loan documents for at least 3 years after loan is paid in full. Here, bucket-level retention is 3 years and the event is the loan being paid in full. In this example, these objects will be held intact for any number of years until the event has occurred (event-based hold on the object is released) and then 3 more years after that. That means retention duration of the objects begins from the moment event-based hold transitioned from true to false.
read / write
generation String
The content generation of this object. Used for object versioning.
read / write
hashCode int
The hash code for this object. [...]
read-only, inherited
id String
The ID of the object, including the bucket name, object name, and generation number.
read / write
kind String
The kind of item this is. For objects, this is always storage#object.
read / write
kmsKeyName String
Cloud KMS Key used to encrypt this object, if the object is encrypted by such a key.
read / write
md5Hash String
MD5 hash of the data; encoded using base64. For more information about using the MD5 hash, see Hashes and ETags: Best Practices.
read / write
Media download link.
read / write
metadata Map<String, String>
User-provided metadata, in key/value pairs.
read / write
metageneration String
The version of the metadata for this object at this generation. Used for preconditions and for detecting changes in metadata. A metageneration number is only meaningful in the context of a particular generation of a particular object.
read / write
name String
The name of the object. Required if not specified by URL parameter.
read / write
owner ObjectOwner
The owner of the object. This will always be the uploader of the object.
read / write
retentionExpirationTime DateTime
A server-determined value that specifies the earliest time that the object's retention period expires. This value is in RFC 3339 format. Note 1: This field is not provided for objects with an active event-based hold, since retention expiration is unknown until the hold is removed. Note 2: This value can be provided even when temporary hold is set (so that the user can reason about policy without having to first unset the temporary hold).
read / write
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
The link to this object.
read / write
size String
Content-Length of the data in bytes.
read / write
storageClass String
Storage class of the object.
read / write
temporaryHold bool
Whether an object is under temporary hold. While this flag is set to true, the object is protected against deletion and overwrites. A common use case of this flag is regulatory investigations where objects need to be retained while the investigation is ongoing. Note that unlike event-based hold, temporary hold does not impact retention expiration time of an object.
read / write
timeCreated DateTime
The creation time of the object in RFC 3339 format.
read / write
timeDeleted DateTime
The deletion time of the object in RFC 3339 format. Will be returned if and only if this version of the object has been deleted.
read / write
timeStorageClassUpdated DateTime
The time at which the object's storage class was last changed. When the object is initially created, it will be set to timeCreated.
read / write
updated DateTime
The modification time of the object metadata in RFC 3339 format.
read / write
