AtomicReferenceArray JDK 1.6)

publicfinal boolean compareAndSet (int i, E expect, E update)

Atomically sets the element at position i to the given updated value if the current value == the expected value.

Atomically sets the element at position i to the given
updated value if the current value == the expected value.
Returns: true if successful. False return indicates that the actual value was not equal to the expected value.
Parameters:
- i - the index
- expect - the expected value
- update - the new value

publicfinal E get (int i)

Gets the current value at position i.

Gets the current value at position i.
Returns: the current value
Parameters:
- i - the index

publicfinal E getAndSet (int i, E newValue)

Atomically sets the element at position i to the given value and returns the old value.

Atomically sets the element at position i to the given
value and returns the old value.
Returns: the previous value
Parameters:
- i - the index
- newValue - the new value

publicfinal void lazySet (int i, E newValue)

Eventually sets the element at position i to the given value.

Eventually sets the element at position i to the given value.
Parameters:
- i - the index
- newValue - the new value
Since: 1.6

publicfinal int length ()

Returns the length of the array.

publicfinal void set (int i, E newValue)

Sets the element at position i to the given value.

Sets the element at position i to the given value.
Parameters:
- i - the index
- newValue - the new value

public String toString ()

Returns the String representation of the current values of array.

publicfinal boolean weakCompareAndSet (int i, E expect, E update)

Atomically sets the element at position i to the given updated value if the current value == the expected value.

May fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.
Returns: true if successful.
Parameters:
- i - the index
- expect - the expected value
- update - the new value
