AtomicIntegerFieldUpdater JDK 1.6)

public int addAndGet ( T obj, int delta)

Atomically adds the given value to the current value of the field of the given object managed by this updater.

publicabstract boolean compareAndSet ( T obj, int expect, int update)

Atomically sets the field of the given object managed by this updater to the given updated value if the current value == the expected value.

Atomically sets the field of the given object managed by this updater
to the given updated value if the current value == the
expected value. This method is guaranteed to be atomic with respect to
other calls to compareAndSet and set, but not
necessarily with respect to other changes in the field.
Returns: true if successful
Parameters:
- obj - An object whose field to conditionally set
- expect - the expected value
- update - the new value
Throws:
- ClassCastException - if {@code obj} is not an instance of the class possessing the field established in the constructor

public int decrementAndGet ( T obj)

Atomically decrements by one the current value of the field of the given object managed by this updater.

publicabstract int get ( T obj)

Gets the current value held in the field of the given object managed by this updater.

public int getAndAdd ( T obj, int delta)

Atomically adds the given value to the current value of the field of the given object managed by this updater.

public int getAndDecrement ( T obj)

Atomically decrements by one the current value of the field of the given object managed by this updater.

public int getAndIncrement ( T obj)

Atomically increments by one the current value of the field of the given object managed by this updater.

public int getAndSet ( T obj, int newValue)

Atomically sets the field of the given object managed by this updater to the given value and returns the old value.

public int incrementAndGet ( T obj)

Atomically increments by one the current value of the field of the given object managed by this updater.

publicabstract void lazySet ( T obj, int newValue)

Eventually sets the field of the given object managed by this updater to the given updated value.

publicstatic AtomicIntegerFieldUpdater< U> newUpdater (Class< U> tclass, String fieldName)

Creates and returns an updater for objects with the given field.

publicabstract void set ( T obj, int newValue)

Sets the field of the given object managed by this updater to the given updated value.

Sets the field of the given object managed by this updater to the
given updated value. This operation is guaranteed to act as a volatile
store with respect to subsequent invocations of compareAndSet.
Parameters:
- obj - An object whose field to set
- newValue - the new value

publicabstract boolean weakCompareAndSet ( T obj, int expect, int update)

Atomically sets the field of the given object managed by this updater to the given updated value if the current value == the expected value.

Atomically sets the field of the given object managed by this updater to the given updated value if the current value == the expected value. This method is guaranteed to be atomic with respect to other calls to compareAndSet and set, but not necessarily with respect to other changes in the field.

May fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.
Returns: true if successful
Parameters:
- obj - An object whose field to conditionally set
- expect - the expected value
- update - the new value
Throws:
- ClassCastException - if {@code obj} is not an instance of the class possessing the field established in the constructor
