Remarks

Class to write to a protobuf stream.

This API is not as convenient or type safe as the standard protobuf classes. If possible, the best recommended library is to use protobuf lite. However, in environments (such as the Android platform itself), a more memory efficient version is necessary.

Each write method takes an ID code from the protoc generated classes and the value to write. To make a nested object, call #start(long) and then #end(long) when you are done.

The ID codes have type information embedded into them, so if you call the incorrect function you will get an IllegalArgumentException.

To retrieve the encoded protobuf stream, call #getBytes().

stream as the top-level objects are finished.

Constructors

ProtoOutputStream()

Construct a ProtoOutputStream with the default chunk size.

ProtoOutputStream(Int32)

Construct a ProtoOutputStream with the given chunk size.

        &lt;p&gt;This is for an in-memory proto. The caller should use {@link #getBytes()</code> for the result.
ProtoOutputStream(Stream)

Construct a ProtoOutputStream that sits on top of an OutputStream.
