Modifier and Type	Method and Description
(package private) void	BucketCache.blockEvicted(BlockCacheKey cacheKey, BucketEntry bucketEntry, boolean decrementBlockNumber, boolean evictedByEvictionProcess) This method is invoked after the bucketEntry is removed from BucketCache.backingMap
private ByteBuffAllocator.Recycler	BucketCache.createRecycler(BucketEntry bucketEntry) Create the ByteBuffAllocator.Recycler for refCnt,which would be used as RefCnt.recycler of HFileBlock.buf returned from BucketCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean).
private boolean	BucketCache.doEvictBlock(BlockCacheKey cacheKey, BucketEntry bucketEntry, boolean evictedByEvictionProcess) Evict the BlockCacheKey and BucketEntry from BucketCache.backingMap and BucketCache.ramCache.
(package private) boolean	BucketCache.evictBucketEntryIfNoRpcReferenced(BlockCacheKey blockCacheKey, BucketEntry bucketEntry) Evict BlockCacheKey and its corresponding BucketEntry only if isRpcRef() is false.
(package private) void	BucketCache.freeBucketEntry(BucketEntry bucketEntry) Free the {BucketEntry actually,which could only be invoked when the refCnt becoming 0.
protected void	BucketCache.putIntoBackingMap(BlockCacheKey key, BucketEntry bucketEntry) Put the new bucket entry into backingMap.
