  - predefinedAcl
```
public static Bucket.BlobWriteOption predefinedAcl(Storage.PredefinedAcl acl)
```
    Returns an option for specifying blob's predefined ACL configuration.
  - doesNotExist
```
public static Bucket.BlobWriteOption doesNotExist()
```
    Returns an option that causes an operation to succeed only if the target blob does not exist. This option can not be provided together with generationMatch(long) or generationNotMatch(long).
  - generationMatch
```
public static Bucket.BlobWriteOption generationMatch(long generation)
```
    Returns an option for blob's data generation match. If this option is used the request will fail if generation does not match the provided value. This option can not be provided together with generationNotMatch(long) or doesNotExist().
  - generationNotMatch
```
public static Bucket.BlobWriteOption generationNotMatch(long generation)
```
    Returns an option for blob's data generation mismatch. If this option is used the request will fail if generation matches the provided value. This option can not be provided together with generationMatch(long) or doesNotExist().
  - metagenerationMatch
```
public static Bucket.BlobWriteOption metagenerationMatch(long metageneration)
```
    Returns an option for blob's metageneration match. If this option is used the request will fail if metageneration does not match the provided value. This option can not be provided together with metagenerationNotMatch(long).
  - metagenerationNotMatch
```
public static Bucket.BlobWriteOption metagenerationNotMatch(long metageneration)
```
    Returns an option for blob's metageneration mismatch. If this option is used the request will fail if metageneration matches the provided value. This option can not be provided together with metagenerationMatch(long).
  - md5Match
```
public static Bucket.BlobWriteOption md5Match(String md5)
```
    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 the provided value.
  - crc32cMatch
```
public static Bucket.BlobWriteOption crc32cMatch(String crc32c)
```
    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 the provided value.
  - encryptionKey
```
public static Bucket.BlobWriteOption encryptionKey(Key key)
```
    Returns an option to set a customer-supplied AES256 key for server-side encryption of the blob.
  - encryptionKey
```
public static Bucket.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
  - userProject
```
public static Bucket.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.
