Method Details

newReference

@InlineMe(replacement="new AtomicReference<>()",
          imports="java.util.concurrent.atomic.AtomicReference")
public static <V> AtomicReference<@Nullable V> newReference()

Creates an AtomicReference instance with no initial value.

Note: this method is now unnecessary and should be treated as deprecated. Instead, use the AtomicReference constructor directly, taking advantage of "diamond" syntax.

Returns:

a new AtomicReference with no initial value

newReference

@InlineMe(replacement="new AtomicReference<>(initialValue)",
          imports="java.util.concurrent.atomic.AtomicReference")
public static <V extends @Nullable Object>
AtomicReference<V> newReference(V initialValue)

Creates an AtomicReference instance with the given initial value.

Note: this method is now unnecessary and should be treated as deprecated. Instead, use the AtomicReference constructor directly, taking advantage of "diamond" syntax.

Parameters:

initialValue - the initial value

Returns:

a new AtomicReference with the given initial value

newReferenceArray

@InlineMe(replacement="new AtomicReferenceArray<>(length)",
          imports="java.util.concurrent.atomic.AtomicReferenceArray")
public static <E> AtomicReferenceArray<@Nullable E> newReferenceArray(int length)

Creates an AtomicReferenceArray instance of given length.

Note: this method is now unnecessary and should be treated as deprecated. Instead, use the AtomicReferenceArray constructor directly, taking advantage of "diamond" syntax.

Parameters:

length - the length of the array

Returns:

a new AtomicReferenceArray with the given length

newReferenceArray

@InlineMe(replacement="new AtomicReferenceArray<>(array)",
          imports="java.util.concurrent.atomic.AtomicReferenceArray")
public static <E extends @Nullable Object>
AtomicReferenceArray<E> newReferenceArray(E[] array)

Creates an AtomicReferenceArray instance with the same length as, and all elements copied from, the given array.

Note: this method is now unnecessary and should be treated as deprecated. Instead, use the AtomicReferenceArray constructor directly, taking advantage of "diamond" syntax.

Parameters:

array - the array to copy elements from

Returns:

a new AtomicReferenceArray copied from the given array
