<pre>
File content, represented as a stream of bytes.
Note: As with all `bytes` fields, protobuffers use a pure binary
representation, whereas JSON representations use base64.

Currently, this field only works for BatchAnnotateFiles requests. It does
not work for AsyncBatchAnnotateFiles requests.

<code>bytes content = 3;</code>

@return This builder for chaining.
