Remarks

A long value that may be updated atomically. See the VarHandle specification for descriptions of the properties of atomic accesses. An AtomicLong is used in applications such as atomically incremented sequence numbers, and cannot be used as a replacement for a java.lang.Long. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.

Constructors

AtomicLong()	Creates a new AtomicLong with initial value `0`.
AtomicLong(Int64)	Creates a new AtomicLong with the given initial value.
AtomicLong(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Acquire	Returns the current value, with memory effects as specified by `VarHandle#getAcquire`.
AndDecrement	Obsolete. Atomically decrements by one the current value.
AndIncrement	Obsolete. Atomically increments by one the current value.
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
Opaque	Returns the current value, with memory effects as specified by `VarHandle#getOpaque`. -or- Sets the value to `newValue`, with memory effects as specified by `VarHandle#setOpaque`.
PeerReference	(Inherited from Object)
Plain	Returns the current value, with memory semantics of reading as if the variable was declared non-`volatile`. -or- Sets the value to `newValue`, with memory semantics of setting as if the variable was declared non-`volatile` and non-`final`.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
