    The account of the authenticated sender
  - listBuckets
```
public ListBucketsResponse listBuckets()
```
    Returns a list of all Bos buckets that the authenticated sender of the request owns.
    Users must authenticate with a valid BCE Access Key ID that is registered with Bos. Anonymous requests cannot list buckets, and users cannot list buckets that they did not create.

    All of the Bos buckets owned by the authenticated sender of the request.
  - listBuckets
```
public ListBucketsResponse listBuckets(ListBucketsRequest request)
```
    Returns a list of all Bos buckets that the authenticated sender of the request owns.

    Parameters:
    request - The request containing all of the options related to the listing of buckets.
    
    Returns:
    All of the Bos buckets owned by the authenticated sender of the request.
  - createBucket
```
public CreateBucketResponse createBucket(String bucketName)
```
    Creates a new Bos bucket with the specified name.
    
    Parameters:
    bucketName - The name of the bucket to create. All buckets in Bos share a single namespace; ensure the bucket is given a unique name.
    
    Returns:
    The newly created bucket.
  - createBucket
```
public CreateBucketResponse createBucket(CreateBucketRequest request)
```
    Creates a new Bos bucket with the specified name.
    
    Parameters:

    Returns:
    The newly created bucket.
  - doesBucketExist
```
public boolean doesBucketExist(String bucketName)
```
    Checks if the specified bucket exists. Bos buckets are named in a global namespace; use this method to determine if a specified bucket name already exists, and therefore can't be used to create a new bucket.
    If invalid security credentials are used to execute this method, the client is not able to distinguish between bucket permission errors and invalid credential errors, and this method could return an incorrect result.
    
    Parameters:
    bucketName - The name of the bucket to check.
    
    Returns:
    The value true if the specified bucket exists in Bos; the value false if there is no bucket in Bos with that name.
  - doesBucketExist
```
public boolean doesBucketExist(DoesBucketExistRequest request)
```
    Checks if the specified bucket exists. Bos buckets are named in a global namespace; use this method to determine if a specified bucket name already exists, and therefore can't be used to create a new bucket.
    If invalid security credentials are used to execute this method, the client is not able to distinguish between bucket permission errors and invalid credential errors, and this method could return an incorrect result.
    
    Parameters:
    request - The request object containing all options for checking a Bos bucket.
    
    Returns:
    The value true if the specified bucket exists in Bos; the value false if there is no bucket in Bos with that name.
  - getBucketAcl
```
public GetBucketAclResponse getBucketAcl(String bucketName)
```
    Gets the ACL for the specified Bos bucket.
    Each bucket and object in Bos has an ACL that defines its access control policy. When a request is made, Bos authenticates the request using its standard authentication procedure and then checks the ACL to verify the sender was granted access to the bucket or object. If the sender is approved, the request proceeds. Otherwise, Bos returns an error.
    
    Parameters:
    bucketName - The name of the bucket whose ACL is being retrieved.
    
    Returns:
    The GetBuckeetAclResponse for the specified Bos bucket.
