[Javaxdelta-devel] Can the dependency on Trove be eliminated?

[Andrew H. <and...@gm...>]

Hi there,

TLDR: Could javaxdelta just use HashMap<Long,Integer> instead of Trove's
LongIntHashMap and, if not, why?

Longer:
I've been playing around with javaxdelta for a while and I'd like to be
able to import it into a few places without having to drag along GNU Trove
as a dependency just for these two files to use LongIntHashMap:

http://sourceforge.net/p/javaxdelta/code/HEAD/tree/trunk/javaxdelta/src/main/java/com/nothome/delta/Checksum.java
http://sourceforge.net/p/javaxdelta/code/HEAD/tree/trunk/javaxdelta/src/main/java/com/nothome/delta/text/Checksum.java

It seems like the dependency was added in r33, but there's no indication in
the commit message of why:
http://sourceforge.net/p/javaxdelta/code/33/

Was there a specific performance concern being addressed here for big files
with lots of chunks, or am I missing something?

Thanks,
Andrew
