  - predefinedAcl
```
public static Storage.BlobWriteOption predefinedAcl(Storage.PredefinedAcl acl)
```
    Returns an option for specifying blob's predefined ACL configuration.
  - doesNotExist
```
public static Storage.BlobWriteOption doesNotExist()
```
    Returns an option that causes an operation to succeed only if the target blob does not exist.
  - generationMatch
```
public static Storage.BlobWriteOption generationMatch()
```
    Returns an option for blob's data generation match. If this option is used the request will fail if generation does not match.
  - generationNotMatch
```
public static Storage.BlobWriteOption generationNotMatch()
```
    Returns an option for blob's data generation mismatch. If this option is used the request will fail if generation matches.
  - metagenerationMatch
```
public static Storage.BlobWriteOption metagenerationMatch()
```
    Returns an option for blob's metageneration match. If this option is used the request will fail if metageneration does not match.
  - metagenerationNotMatch
```
public static Storage.BlobWriteOption metagenerationNotMatch()
```
    Returns an option for blob's metageneration mismatch. If this option is used the request will fail if metageneration matches.
  - md5Match
```
public static Storage.BlobWriteOption md5Match()
```
    Returns an option for blob's data MD5 hash match. If this option is used the request will fail if blobs' data MD5 hash does not match.
  - crc32cMatch
```
public static Storage.BlobWriteOption crc32cMatch()
```
    Returns an option for blob's data CRC32C checksum match. If this option is used the request will fail if blobs' data CRC32C checksum does not match.
  - encryptionKey
```
public static Storage.BlobWriteOption encryptionKey(Key key)
```
    Returns an option to set a customer-supplied AES256 key for server-side encryption of the blob.
  - encryptionKey
```
public static Storage.BlobWriteOption encryptionKey(String key)
```
    Returns an option to set a customer-supplied AES256 key for server-side encryption of the blob.
    
    Parameters:
    
    key - the AES256 encoded in base64
  - kmsKeyName
```
public static Storage.BlobWriteOption kmsKeyName(String kmsKeyName)
```
    Returns an option to set a customer-managed KMS key for server-side encryption of the blob.
    
    Parameters:
    
    kmsKeyName - the KMS key resource id
  - userProject
```
public static Storage.BlobWriteOption userProject(String userProject)
```
    Returns an option for blob's billing user project. This option is only used by the buckets with 'requester_pays' flag.
