Deflater.setDictionary

[Dr. Carsten Leue]

I would like to initialize the java.util.zip.Deflater object with a
precalculated dictionary. The documentation is very sparse, it just tells to
pass in a byte array, but nothing about the content of this array. When I
use an arbitrary array I get an IllegalArgumentException. The documentation
says that this is due to an invalid dictionary format. But what is the
correct format?

Best regards
Carsten

You may find the documentation for the underlying ZLib implementation more
helpful -- or maybe not since it's still not ideally detailed. It's better
than the JavaDoc for the Java wrapper classes, anyway.

HTH (at least a little).
