Interface SegmentReader.CoreClosedListener

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.

Method Summary

void	onClose(Object ownerCoreCacheKey) Invoked when the shared core of the original SegmentReader has closed.
