13c666adef performance hack to ObjectIndex put() method:
Java standard classes provide a Map Interface, that has a put() method that returns the object that was replaced by the object that was the argument of the put call. The kelondro ObjectIndex defined a put method in the same way, that means it also returned the previous value of the Entry object before the put call. However, this value was not used by the calling code in the most cases. Omitting a return of the previous value would cause some performance benefit. This change implements a put method that does not return the previous value to reflect the common use. Omitting the return of previous values will cause some benefit in performance. The functionality to get the previous value is still maintained, and provided with a new 'replace' method.

3e4c28e188 enhanced count feature for kelondroRowSet. This is about twice as fast as before. Should speed up the collection analysis (half time!)

100247bdda added also an export and delete-feature to the URLAnalysis. This completes the clean-up feature for URLs. To do a complete clean-up of the url database, start the following:
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -incollection DATA/INDEX/freeworld/TEXT/RICOLLECTION used.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -diffurlcol DATA/INDEX/freeworld/TEXT used.dump diffurlcol.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -export DATA/INDEX/freeworld/TEXT xml urls.xml diffurlcol.dump
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -delete DATA/INDEX/freeworld/TEXT diffurlcol.dump

The export-feature is optional, the purpose of that function is to provide a back-up function for URLs to be deleted. The export function can also be used to create html files with embedded links and simple text-files. Simply replace the 'xml' word with 'html' or 'text'. The last argument in the cann, the diffurlcol.dump value, can also be omitted. This will cause that the complete URL database is exported. This is an alternative to the Web-Interface based export function.

The delete-feature is the only destructive method of the four presented here. Please use it with care. It is better to make a back-up of the url database files before starting the deletion.

60078cf322 added next tool for url analysis: check for references, that occur in the URL-DB but not in the RICOLLECTIONS
to use this, you must user the -incollection command before (see SVN 5687) and you need a 
used.dump file that has been produced with that process.

Now you can use that file, to do a URL-hash compare with the urls in the URL-DB. To do that, execute
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -diffurlcol DATA/INDEX/freeworld/TEXT used.dump diffurlcol.dump
or use different names for the dump files or more memory.

As a result, you get the file diffurlcol.dump which contains all the url hashes that occur in the URL database, but not in the collections.
The file has the format
{hash-12}*
that means: 12 byte long hashes are listed without any separation.

The next step could be to process this file and delete all these URLs with the computed hashes, or to export them before deletion.

d64836c34f added statistical analysis of URL reference
use that with the following command on a linux shell:
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -incollection DATA/INDEX/freeworld/TEXT/RICOLLECTION used.dump
for freeworld indexes.
