Re: [Jazzlib-developers] type of compression using jazzlib

[John L. <je...@pi...>]

Hi Trevor

The java.util.zip interface and implementations allow you to read and
write ".zip" files.=20

This file format is the same as used by other zip tools.

The compression formats used are the same as those provided by the zlib
library.=20

So I think the answer to your question is 'yes'.

It occurred to me that some environments (J2ME) might want to have
support for decompressing a datastream without shipping the bytecode for
decompression. It should be possible to separate these classes and work
out exactly what the dependencies are.

You might have problems using code like ZipFile because it depends on
HashMap and a bunch of other classes from the J2SE libraries that may
not be available in your J2ME environment. It shouldn't be too hard to
rewrite it so that it works.=20
