(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.
Cacheable	ByteBufferIOEngine.read(BucketEntry be)
Cacheable	ExclusiveMemoryMmapIOEngine.read(BucketEntry be)
Cacheable	FileIOEngine.read(BucketEntry be)	Transfers data from file to the given byte buffer
