public abstract int	readRawVarint32() Read a raw Varint from the stream.
public static int	readRawVarint32(final int firstByte, final InputStream input) Like `readRawVarint32(InputStream)`, but expects that the caller has already read one byte.
pack-priv static int	readRawVarint32(final InputStream input) Reads a varint from the input one byte at a time, so that it does not read any bytes after the end of the varint.

public abstract long	readUInt64() Read a `uint64` field value from the stream.
public abstract void	readUnknownGroup(final int fieldNumber, final MessageLite.Builder builder) Deprecated UnknownFieldSet.Builder now implements MessageLite.Builder, so you can just call `readGroup`. Reads a `group` field value from the stream and merges it into the given `UnknownFieldSet`.
public abstract void	resetSizeCounter() Resets the current size counter to zero (see `setSizeLimit(int)`).
public final int	Returns: the old limit. setRecursionLimit(final int limit) Set the maximum message recursion depth.
