Constructor Detail

GridCacheAtomicReferenceImpl

public GridCacheAtomicReferenceImpl()

Empty constructor required by Externalizable.

GridCacheAtomicReferenceImpl

public GridCacheAtomicReferenceImpl(String name,
                                    GridCacheInternalKey key,
                                    IgniteInternalCache<GridCacheInternalKey,GridCacheAtomicReferenceValue<T>> atomicView)

Default constructor.

Parameters:

name - Atomic reference name.

key - Atomic reference key.

atomicView - Atomic projection.

Method Detail

name

public String name()

Name of atomic reference.

Specified by:

name in interface IgniteAtomicReference<T>

Overrides:

name in class AtomicDataStructureProxy<GridCacheAtomicReferenceValue<T>>

Returns:

Datastructure name.

get

public T get()

Gets current value of an atomic reference.

Specified by:

get in interface IgniteAtomicReference<T>

Returns:

current value of an atomic reference.

set

public void set(T val)

Unconditionally sets the value.

Specified by:

set in interface IgniteAtomicReference<T>

Parameters:

val - Value.

compareAndSet

public boolean compareAndSet(T expVal,
                             T newVal)

Conditionally sets the new value. That will be set if expVal is equal to current value respectively.

Specified by:

compareAndSet in interface IgniteAtomicReference<T>

Parameters:

expVal - Expected value.

newVal - New value.

Returns:

Result of operation execution. If true than value have been updated.

compareAndSetAndGet

public T compareAndSetAndGet(T newVal,
                             T expVal)

Compares current value with specified value for equality and, if they are equal, replaces current value.

Parameters:

newVal - New value to set.

expVal - Expected value.

Returns:

Original value.

close

public void close()

Removes this atomic reference.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface IgniteAtomicReference<T>

                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
