## Instance Methods

Permanently deletes an empty bucket.

Returns metadata for the specified bucket.

Creates a new bucket.

Retrieves a list of buckets for a given project.

Retrieves the next page of results.

### Method Details

`delete(bucket, ifMetagenerationMatch=None, ifMetagenerationNotMatch=None)`

    Permanently deletes an empty bucket.

    Args:
      bucket: string, Name of a bucket. (required)
      ifMetagenerationMatch: string, If set, only deletes the bucket if its metageneration matches this value.
      ifMetagenerationNotMatch: string, If set, only deletes the bucket if its metageneration does not match this value.

`get(bucket, projection=None, ifMetagenerationMatch=None, ifMetagenerationNotMatch=None)`

    Returns metadata for the specified bucket.

    Args:
      bucket: string, Name of a bucket. (required)
      projection: string, Set of properties to return. Defaults to noAcl.
        Allowed values
          full - Include all properties.
          noAcl - Omit owner, acl and defaultObjectAcl properties.
      ifMetagenerationMatch: string, Makes the return of the bucket metadata conditional on whether the bucket's current metageneration matches the given value.
      ifMetagenerationNotMatch: string, Makes the return of the bucket metadata conditional on whether the bucket's current metageneration does not match the given value.

    Returns:

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`patch(bucket, body, projection=None, ifMetagenerationMatch=None, predefinedDefaultObjectAcl=None, predefinedAcl=None, ifMetagenerationNotMatch=None)`

    Updates a bucket. Changes to the bucket will be readable immediately after writing, but configuration changes may take time to propagate. This method supports patch semantics.

    Args:
      bucket: string, Name of a bucket. (required)
      body: object, The request body. (required)
