<div class="block">This interface provides a rich API for working with distributed atomic reference.
<p>
<h1 class="header">Functionality</h1>
Distributed atomic reference includes the following main functionality:
<ul>
<li>
Method <a href="../../../org/apache/ignite/IgniteAtomicReference.html#get--"><code>get()</code></a> gets current value of an atomic reference.
</li>
<li>
Method <a href="../../../org/apache/ignite/IgniteAtomicReference.html#set-T-"><code>set(Object)</code></a> unconditionally sets the value in the an atomic reference.
</li>
<li>
Methods <code>compareAndSet(...)</code> conditionally set the value in the an atomic reference.
</li>
<li>
Method <a href="../../../org/apache/ignite/IgniteAtomicReference.html#name--"><code>name()</code></a> gets name of atomic reference.
</li>
</ul>
<h1 class="header">Creating Distributed Atomic Reference</h1>
Instance of distributed atomic reference can be created by calling the following method:
<ul>
<li><a href="../../../org/apache/ignite/Ignite.html#atomicReference-java.lang.String-T-boolean-"><code>Ignite.atomicReference(String, Object, boolean)</code></a></li>
