Package org.cache2k.core

Class IntHeapCache<V>

java.lang.Object

org.cache2k.core.BaseCache<K,V>

org.cache2k.core.HeapCache<Integer,V>

org.cache2k.core.IntHeapCache<V>

All Implemented Interfaces:

AutoCloseable, org.cache2k.Cache<Integer,V>, InternalCache<Integer,V>, InternalCacheCloseContext, HeapCacheForEviction<Integer,V>, TimerEventListener<Integer,V>, org.cache2k.DataAware<Integer,V>, org.cache2k.KeyValueSource<Integer,V>

public class IntHeapCache<V>
extends HeapCache<Integer,V>

Overwrite methods so the integer value gets stored directly in the Entry.hashCode field and Entry.value is set to null.

Method Detail

extractIntKeyObj

public Integer extractIntKeyObj(Integer key)

Description copied from class: HeapCache

The key object or null, for integer keyed caches

Overrides:

extractIntKeyObj in class HeapCache<Integer,V>

extractIntKeyValue

public int extractIntKeyValue(Integer key,
                              int hc)

Description copied from class: HeapCache

Modified hash code or integer value for integer keyed caches

Overrides:

extractIntKeyValue in class HeapCache<Integer,V>

extractModifiedHash

public int extractModifiedHash(Entry e)

Overrides:

extractModifiedHash in class HeapCache<Integer,V>

extractKeyObj

public Integer extractKeyObj(Entry<Integer,V> e)

Overrides:

extractKeyObj in class HeapCache<Integer,V>

createHashTable

public Hash2<Integer,V> createHashTable()

Modified hash table implementation. Rehash needs to calculate the correct hash code again.

Overrides:

createHashTable in class HeapCache<Integer,V>
