Class AtomicHashMap<K,V>

java.lang.Object
  org.infinispan.atomic.AtomicHashMap<K,V>

Type Parameters:

K -

V -

All Implemented Interfaces:

Cloneable, Map<K,V>, AtomicMap<K,V>, DeltaAware

@NotThreadSafe
public class AtomicHashMap<K,V>
extends Object
implements AtomicMap<K,V>, DeltaAware, Cloneable

Note that for replication to work properly, this class requires that all writes take place within the scope of an ongoing transaction or batch.

Method Detail

newInstance

public static AtomicHashMap newInstance(Cache cache,
                                        Object cacheKey)

Construction only allowed through this factory method. This factory is intended for use internally by the CacheDelegate. User code should use org.infinispan.atomic.AtomicMapCache#getAtomicMap(Object).

commit

public void commit()

Description copied from interface: DeltaAware

Indicate that all deltas collected to date has been extracted (via a call to DeltaAware.delta()) and can be discarded.

Specified by:

commit in interface DeltaAware

size

public int size()

Specified by:

size in interface Map<K,V>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K,V>

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface Map<K,V>

containsValue

public boolean containsValue(Object value)

Specified by:

containsValue in interface Map<K,V>

get

public V get(Object key)

Specified by:

get in interface Map<K,V>

keySet

public Set<K> keySet()

Specified by:

keySet in interface Map<K,V>

values

public Collection<V> values()

Specified by:

values in interface Map<K,V>

entrySet

public Set<Map.Entry<K,V>> entrySet()

Specified by:

entrySet in interface Map<K,V>

put

public V put(K key,
             V value)

Specified by:

put in interface Map<K,V>

remove

public V remove(Object key)

Specified by:

remove in interface Map<K,V>

putAll

public void putAll(Map<? extends K,? extends V> t)

Specified by:

putAll in interface Map<K,V>

clear

public void clear()

Specified by:

getProxy

public AtomicMap<K,V> getProxy(Cache cache,
                               Object mapKey,
                               BatchContainer batchContainer,
                               InvocationContextContainer icc)

delta

public Delta delta()

Description copied from interface: DeltaAware

Extracts changes made to implementations, in an efficient format that can easily and cheaply be serialized and deserialized. This method can only be called once for each changeset as it wipes its internal changelog when generating and submitting the delta to the caller.

Specified by:

delta in interface DeltaAware

Returns:

an instance of Delta

copyForWrite

public AtomicHashMap copyForWrite()

toString

public String toString()

Overrides:

toString in class Object

initForWriting

public void initForWriting()

Initializes the delta instance to start recording changes.
