Class ConcurrentLinkedHashCache<K,V>
java.lang.Object
org.apache.cassandra.cache.ConcurrentLinkedHashCache<K,V>
- All Implemented Interfaces:
- ICache<K,V>
public class ConcurrentLinkedHashCache<K,V>
- extends java.lang.Object
- implements ICache<K,V>
Wrapper so CLHM can implement ICache interface.
(this is what you get for making library classes final.)

get
public V get(K key)
- Specified by:
get in interface ICache<K,V>
put
public void put(K key,
V value)
- Specified by:
put in interface ICache<K,V>
putIfAbsent
public boolean putIfAbsent(K key,
V value)
- Specified by:
putIfAbsent in interface ICache<K,V>
replace
public boolean replace(K key,
V old,
V value)
- Specified by:
replace in interface ICache<K,V>
remove
public void remove(K key)
- Specified by:
remove in interface ICache<K,V>

public java.util.Set<K> keySet()
- Specified by:
keySet in interface ICache<K,V>
hotKeySet
public java.util.Set<K> hotKeySet(int n)
- Specified by:
hotKeySet in interface ICache<K,V>
containsKey
public boolean containsKey(K key)
- Specified by:

isPutCopying
public boolean isPutCopying()
- Specified by:
isPutCopying in interface ICache<K,V>
- Returns:
- true if the cache implementation inherently copies the cached values; otherwise,
the caller should copy manually before caching shared values like Thrift ByteBuffers.
