 org.archive.io.RepositionableInputStream
| RepositionableInputStream | | public class RepositionableInputStream extends BufferedInputStream implements RepositionableStream(Code) | | Wrapper around an
InputStream to make a primitive Repositionable
stream. Uses a
BufferedInputStream . Calls mark on every read so
we'll remember at least the last thing read (You can only backup on the
last thing read -- not last 2 or 3 things read). Used by
GzippedInputStream when reading streams over a network. Wraps a
HTTP, etc., stream so we can back it up if needs be after the
GZIP inflater has done a fill of its full buffer though it only needed
the first few bytes to finish decompressing the current GZIP member.
TODO: More robust implementation. Tried to use the it.unimi.dsi.io
FastBufferdInputStream but relies on FileChannel ByteBuffers and if not
present -- as would be the case reading from a network stream, the main
application for this instance -- then it expects the underlying stream
implements RepositionableStream interface so chicken or egg problem.
