Class LazyAtomicReference<V>

java.lang.Object

java.util.concurrent.atomic.AtomicReference<V>

jetbrains.buildServer.util.impl.LazyAtomicReference<V>

Type Parameters:

V -

All Implemented Interfaces:

Serializable

public class LazyAtomicReference<V>
extends AtomicReference<V>

This class is a simple alternative to Lazy. It can be better in cases when memory footprint is important, because Lazy requires creation of an anonymous class which can capture "this" of the outer instance. It is also a bit simpler to use than Lazy because under the hood this is still an AtomicReference with all its convenient atomic methods.

2020.1
