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 Summary

Modifier and Type	Method	Description
StampedHash<Integer,V>	createHashTable()	Modified hash table implementation.
Integer	keyObjFromEntry(Entry<Integer,V> e)	Either returns the stored key object or the integer object created from the hashCode field.
int	spreadHashFromEntry(Entry e)

Constructor Detail

IntHeapCache

public IntHeapCache(InternalCacheBuildContext<Integer,V> ctx)

Method Detail

toEntryKey

public Integer toEntryKey(Integer key)

Description copied from class: HeapCache

The key object or null, for integer keyed caches

Overrides:

toEntryKey in class HeapCache<Integer,V>

toStoredHashCodeOrKey

public int toStoredHashCodeOrKey(Integer key,
                                 int hc)

Description copied from class: HeapCache

We store either the spread hash code or the raw integer key in the hash table

Overrides:

toStoredHashCodeOrKey in class HeapCache<Integer,V>

spreadHashFromEntry

public int spreadHashFromEntry(Entry e)

Overrides:

spreadHashFromEntry in class HeapCache<Integer,V>

keyObjFromEntry

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

Description copied from class: HeapCache

Either returns the stored key object or the integer object created from the hashCode field.

Overrides:

keyObjFromEntry in class HeapCache<Integer,V>

createHashTable

public StampedHash<Integer,V> createHashTable()

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

Overrides:

createHashTable in class HeapCache<Integer,V>
