[compress] unzip a file in one go API?
Can you unzip a file in one shot using Apache Commons Compress?
>From https://wiki.apache.org/commons/Compress, I see:
final InputStream <https://wiki.apache.org/commons/InputStream> is = new
FileInputStream <https://wiki.apache.org/commons/FileInputStream>(input);
ArchiveInputStream <https://wiki.apache.org/commons/ArchiveInputStream> in =
new ArchiveStreamFactory<https://wiki.apache.org/commons/ArchiveStreamFactory>().createArchiveInputStream("zip",
is);
ZipArchiveEntry <https://wiki.apache.org/commons/ZipArchiveEntry> entry = (
ZipArchiveEntry
<https://wiki.apache.org/commons/ZipArchiveEntry>)in.getNextEntry();
OutputStream <https://wiki.apache.org/commons/OutputStream> out = new
FileOutputStream <https://wiki.apache.org/commons/FileOutputStream>(new
File(dir, entry.getName()));
IOUtils.copy(in, out);
out.close();
in.close();
But that looks like you (1) need to loop though the ZIP entries and (2)
create dirs yourself.
What am I missing?
How about adding a decompress(source, dest) API?
Thank you,
Gary

Nothing :-)

Why not. Now we have a good "base" api, we really could need some cool
tools around it. one is already in svn, its a class called "Lister"
which outputs the content of an archive.

What Christian said.

COMPRESS-118
Actually I'd like us to get Compress 1.3 out of the door soonish (more
on that on the dev list later) and start discussing changes to the lower
level API for 2.0, some of which might affect how we'd do higher level
APIs.
