classes

Protocol Buffers are a way of encoding structured data in an
efficient yet extensible format. Google uses Protocol Buffers for almost all
of its internal RPC protocols and file formats.  Additional
documentation is available in the arXiv.org preprint "RProtoBuf:
Efficient Cross-Language Data Serialization in R" by Eddelbuettel,
Stokely, and Ooms (2014) at <http://arxiv.org/abs/1401.7372>.

Class <code>"ZeroCopyInputStream"</code>, directly.

Extends

<dl>
		<dt>close</dt><dd><code>signature(con="FileInputStream")</code>: 
			Flushes any buffers and closes the underlying file. 
			Returns false if an error occurs during the process; use <code>GetErrno</code> to examine the error
		</dd> <dt>GetErrno</dt><dd><code>signature(object="FileInputStream")</code>: 
			If an I/O error has occurred on this file descriptor, this is the errno from that error.
			Otherwise, this is zero. Once an error occurs, the stream is broken and all subsequent operations will fail.
		</dd> <dt>SetCloseOnDelete</dt><dd><code>signature(object="FileInputStream")</code>: 
			set the close on delete behavior.
