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:

Closeable, AutoCloseable, org.cache2k.AdvancedKeyValueSource<Integer,V>, org.cache2k.Cache<Integer,V>, CanCheckIntegrity, InternalCache<Integer,V>, org.cache2k.IntCache<V>, org.cache2k.IntKeyValueSource<V>, org.cache2k.IntKeyValueStore<V>, org.cache2k.KeyValueSource<Integer,V>, org.cache2k.KeyValueStore<Integer,V>

public class IntHeapCache<V>
extends HeapCache<Integer,V>
implements org.cache2k.IntCache<V>

Overwrite methods so the integer value gets stored directly in the CompactEntry.hashCode field and CompactEntry.key is set to null. Defines methods from IntCache so no autoboxing needs to be done in the access path.

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>

peek

public V peek(int key)

Specified by:

peek in interface org.cache2k.IntCache<V>

containsKey

public boolean containsKey(int key)

Specified by:

containsKey in interface org.cache2k.IntCache<V>

put

public void put(int key,
                V value)

Specified by:

put in interface org.cache2k.IntKeyValueStore<V>

get

public V get(int key)

Specified by:

get in interface org.cache2k.IntKeyValueSource<V>

remove

public void remove(int key)

Specified by:

remove in interface org.cache2k.IntKeyValueStore<V>
