actually, I made a TracerDirectory that shows for searching, it really makes
very few calls into the Directory. now I admit that running this test using
the demo.IndexFiles and demo.SearchIndex (or whatever it is) isn't
necessarily a true reflection of the IO of lucene in a real world situation,
but with a CachingDirectory similar to the TracingDirectory snippet below, I
think you could get some wicked speed.
Looking forward to throwing a lucene indexer into an EJB2.0 Message Driven
Bean,
Noah
===========================================
public final class TracingDirectory extends Directory {
private Directory passThroughDirectory = null;
public TracingDirectory(Directory passThroughDirectory) {
this.passThroughDirectory = passThroughDirectory;
}
public String[] list()
throws IOException, SecurityException {
System.err.println("list()");
return this.passThroughDirectory.list();
}
<snip />
}
