Add toString() or getName() method to IndexReader
-------------------------------------------------
Key: LUCENE-1923
URL: https://issues.apache.org/jira/browse/LUCENE-1923
Project: Lucene - Java
Issue Type: Wish
Components: Index
Reporter: Tim Smith
It would be very useful for debugging if IndexReader either had a getName()
method, or a toString() implementation that would get a string identification
for the reader.
for SegmentReader, this would return the same as getSegmentName()
for Directory readers, this would return the "generation id"?
for MultiReader, this could return something like "multi(sub reader name, sub
reader name, sub reader name, ...)
right now, i have to check instanceof for SegmentReader, then call
getSegmentName(), and for all other IndexReader types, i would have to do
something like get the IndexCommit and get the generation off it (and this may
throw UnsupportedOperationException, at which point i have would have to
recursively walk sub readers and try again)
I could work up a patch if others like this idea
