Constructors

Name	Description
AtomicReference()	Creates a new AtomicReference with null initial value.
AtomicReference(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.
AtomicReference(Object)	Creates a new AtomicReference with the given initial value.

Properties

Name	Description
Acquire	Returns the current value, with memory effects as specified by `VarHandle#getAcquire`.
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	Gets the identity hash code assigned to this Java peer by the interop runtime. (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	Gets the JNI object reference for this Java peer. (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.

Methods

Name	Description
AccumulateAndGet(Object, IBinaryOperator)	Atomically updates (with memory effects as specified by `VarHandle#compareAndSet`) the current value with the results of applying the given function to the current and given values, returning the updated value.
Clone()	Creates and returns a copy of this object. (Inherited from Object)
