public static interface SegmentReader.CoreClosedListener
Called when the shared core for this SegmentReader is closed.This listener is called only once all SegmentReaders sharing the same core are closed. At this point it is safe for apps to evict this reader from any caches keyed on
SegmentReader.getCoreCacheKey()
. This is the same interface thatFieldCache
uses, internally, to evict entries.- WARNING: This API is experimental and might change in incompatible ways in the next release.
