Stefan Bodewig commented on COMPRESS-327:
-----------------------------------------
Current git master's 7z package is able to deal with {{SeekableByteChannel}}
and doesn't require {{RandomAccessFile}} anymore. I plan to do the same to the
zip package. The current code could be improved to use cached {{ByteBuffer}}s
in order to reduce memory consumption.
We may want to add an implementation of {{SeekableByteChannel}} wrapped around
a {{byte[]}}}.

> ZipFile (and SevenZFile) currently require a File argument, but it would be
> nice to support in-memory byte buffers rather than requiring temp files.
> Perhaps create a new SeekableInputStream class (or SeekableDataInput
> interface) and add corresponding constructors.
> For convenience, perhaps also add a utility class that wraps a ByteBuffer
> and/or byte[] and implements the new interface.
> (The sevenz package appears to have a similar limitation, so it might make
> sense to add the support there at the same time, but I personally don't have
> a need for that.)
