Method Summary

Modifier and Type	Method	Description
InternalCacheEntry<K,V>	peek(Object key)	Peaks at a value for the given key.
default void	putNoReturn(K key, InternalCacheEntry<K,V> value)	Same as Map.put(Object, Object) except that the map is not required to return a value.
void	touchAll(long currentTimeMillis)	Touches all entries in the map setting the recency timestamps for both expiration eviction appropriately.
boolean	touchKey(Object key, long currentTimeMillis)	Touches the entry for the given key in this map.

Method Details

peek

InternalCacheEntry<K,V> peek(Object key)

Peaks at a value for the given key. Note that this does not update any expiration or eviction information when this is performed on the map, unlike the get method.

Parameters:

key - The key to find the value for

Returns:

The value mapping to this key

touchKey

boolean touchKey(Object key,
 long currentTimeMillis)

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

Parameters:

key - key to touch

currentTimeMillis - the recency timestamp to set

Returns:

whether the entry was touched or not

touchAll

void touchAll(long currentTimeMillis)

Touches all entries in the map setting the recency timestamps for both expiration eviction appropriately.

Parameters:

currentTimeMillis - the recency timestamp to set

putNoReturn

default void putNoReturn(K key,
 InternalCacheEntry<K,V> value)

Same as Map.put(Object, Object) except that the map is not required to return a value. This can be useful when retrieving a previous value may incur additional costs.

Parameters:

key - key to insert for the value

value - the value to insert into this map
