Interface SegmentReader.ICoreDisposedListener

Called when the shared core for this SegmentReader is disposed.

This listener is called only once all SegmentReaders sharing the same core are disposed. At this point it is safe for apps to evict this reader from any caches keyed on CoreCacheKey. This is the same interface that IFieldCache uses, internally, to evict entries.

NOTE: This was CoreClosedListener in Lucene.
