SegmentReader.CoreClosedListener (Lucene 3.6.2 API)

Enclosing class:

SegmentReader
```
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 that FieldCache uses, internally, to evict entries.

WARNING: This API is experimental and might change in incompatible ways in the next release.
