Uses of LruCachedBlock in org.apache.hadoop.hbase.io.hfile

Fields in org.apache.hadoop.hbase.io.hfile with type parameters of type LruCachedBlock

Modifier and Type	Field and Description
private ConcurrentHashMap<BlockCacheKey,LruCachedBlock>	LruBlockCache.map Defined the cache map as ConcurrentHashMap here, because in LruBlockCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean), we need to guarantee the atomicity of map#computeIfPresent (key, func).
private ConcurrentHashMap<BlockCacheKey,LruCachedBlock>	LruAdaptiveBlockCache.map Defined the cache map as ConcurrentHashMap here, because in LruAdaptiveBlockCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean), we need to guarantee the atomicity of map#computeIfPresent (key, func).
private org.apache.hbase.thirdparty.com.google.common.collect.MinMaxPriorityQueue<LruCachedBlock>	LruCachedBlockQueue.queue

Methods in org.apache.hadoop.hbase.io.hfile that return LruCachedBlock

Modifier and Type	Method and Description
LruCachedBlock	LruCachedBlockQueue.poll() Returns The next element in this queue, or null if the queue is empty.
LruCachedBlock	LruCachedBlockQueue.pollLast() Returns The last element in this queue, or null if the queue is empty.

Methods in org.apache.hadoop.hbase.io.hfile that return types with arguments of type LruCachedBlock

Modifier and Type	Method and Description
(package private) Map<BlockCacheKey,LruCachedBlock>	LruBlockCache.getMapForTests()
(package private) Map<BlockCacheKey,LruCachedBlock>	LruAdaptiveBlockCache.getMapForTests()

Methods in org.apache.hadoop.hbase.io.hfile with parameters of type LruCachedBlock

Modifier and Type	Method and Description
void	LruCachedBlockQueue.add(LruCachedBlock cb) Attempt to add the specified cached block to this queue.
void	LruBlockCache.BlockBucket.add(LruCachedBlock block)
void	LruAdaptiveBlockCache.BlockBucket.add(LruCachedBlock block)
int	LruCachedBlock.compareTo(LruCachedBlock that)
protected long	LruBlockCache.evictBlock(LruCachedBlock block, boolean evictedByEvictionProcess) Evict the block, and it will be cached by the victim handler if exists && block may be read again later
protected long	LruAdaptiveBlockCache.evictBlock(LruCachedBlock block, boolean evictedByEvictionProcess) Evict the block, and it will be cached by the victim handler if exists && block may be read again later
private long	LruBlockCache.updateSizeMetrics(LruCachedBlock cb, boolean evict) Helper function that updates the local size counter and also updates any per-cf or per-blocktype metrics it can discern from given LruCachedBlock
private long	LruAdaptiveBlockCache.updateSizeMetrics(LruCachedBlock cb, boolean evict) Helper function that updates the local size counter and also updates any per-cf or per-blocktype metrics it can discern from given LruCachedBlock
