Load, into the specified `value`, the value associated with the specified `key` in this cache. If the optionally specified `modifyEvictionQueue` is `true` and the eviction policy is LRU, then move the cached item to the back of the eviction queue. Return 0 on success, and 1 if `key` does not exist in this cache. Note that a write lock is acquired only if this queue is modified.
