Ok, but by inspecting the java code, this was pretty trivial to
implement in Python. Only curiosity, but do you think the java version
would be (significantly) faster. I'm not sure I understand the
performance implications from the jcc bridge.
I don't know. How about measuring it ?
The jcc bridge involves converting some literals from java to python
(such as strings), releasing the GIL (global interpreter lock) when
leaving python and reacquiring it when returnig.
The jcc bridge also keeps track of the java objects returned to python
so that they don't get garbage collected until python no longer uses
them. This is implemented via a C++ multimap.
It's been shown before that using a python HitCollector (used in a very
tight loop by the Lucene core) is significantly slower than using the
java equivalent [1].
Ok, I will try to measure it.
After I understand the makefile jar/java stuff better - and I guess thats
after my theoretical CS Exams next Week ;).
