Struct AtomicReference<T>

Provides container with atomic operations for the reference type.

Implements

IEquatable<T>

ISerializable

Namespace: DotNext.Threading

Assembly: DotNext.dll

Syntax

public struct AtomicReference<T> : IEquatable<T>, ISerializable where T : class

Type Parameters

Name	Description
T	Type of object to be stored inside of container.

Remarks

Use this structure in the declaration of integer value. volatile specifier is not needed for such field. Do not pass this structure by value into another methods, otherwise you will get a local copy of the reference not referred to the field.
