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

Modifier and Type	Method and Description
private Cacheable	LruBlockCache.asReferencedHeapBlock(Cacheable buf) The block cached in LRUBlockCache will always be an heap block: on the one side, the heap access will be more faster then off-heap, the small index block or meta block cached in CombinedBlockCache will benefit a lot.
Cacheable	LruBlockCache.getBlock(BlockCacheKey cacheKey, boolean caching, boolean repeat, boolean updateCacheMetrics) Get the buffer of the block with the specified name.
Cacheable	BlockCache.getBlock(BlockCacheKey cacheKey, boolean caching, boolean repeat, boolean updateCacheMetrics) Fetch block from cache.

Cacheable	LruCachedBlock.getBuffer()
default Cacheable	Cacheable.retain() Increase its reference count, and only when no reference we can free the object's memory.
