Instance Method Details

#==(other) ⇒ Object

def ==(other)
  self.name == other.name and self.service == other.service
end

#destroy(force = false) ⇒ Object

Destroys given bucket. Raises an S3::Error::BucketNotEmpty exception if the bucket is not empty. You can destroy non-empty bucket passing true (to force destroy)
