Interface Summary

HeapSize	Implementations can be asked for an estimate of their size in bytes.

Class Summary

Class	Description
CachedBlock	Represents an entry in the configurable block cache.
CachedBlockQueue	A memory-bound queue that will grow until an element brings total size >= maxSize.
LruBlockCache	A block cache implementation that is memory-aware using HeapSize, memory-bound using an LRU eviction algorithm, and concurrent: backed by a ConcurrentHashMap and with a non-blocking eviction thread giving constant-time LruBlockCache.cacheBlock(java.lang.String, byte[], boolean) and LruBlockCache.getBlock(java.lang.String) operations.

LruBlockCacheConfiguration
LruBlockCacheConfiguration.Builder
LruBlockCacheManager
SynchronousLoadingBlockCache	This class implements loading in such a way that load operations for the same block will not run concurrently.
