Constructor Detail

OffHeapConcurrentMap

public OffHeapConcurrentMap(int desiredSize,
                            OffHeapMemoryAllocator allocator,

Method Detail

touchKey

public boolean touchKey(Object key,
                        long currentTimeMillis)

Description copied from interface: TouchableMap

Touches the entry for the given key in this map. This method will update any recency timestamps for both expiration or eviction as needed.

Specified by:

Parameters:

key - key to touch

currentTimeMillis - the recency timestamp to set

Returns:

whether the entry was touched or not
