| Distributed atomic reference includes the following main functionality: |
| <ul> |
| <li> |
| Method <a href="../../../org/apache/ignite/IgniteAtomicReference.html#get()"><code>get()</code></a> synchronously gets current value of an atomic reference. |
| </li> |
| <li> |
| Method <a href="../../../org/apache/ignite/IgniteAtomicReference.html#set(T)"><code>set(Object)</code></a> synchronously and unconditionally sets the value in the an atomic reference. |
| </li> |
| <li> |
| Methods <code>compareAndSet(...)</code> synchronously and conditionally set the value in the an atomic reference. |
| </li> |
| </ul> |
| All previously described methods have asynchronous analogs. |
| <ul> |
| <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,%20T,%20boolean)"><code>Ignite.atomicReference(String, Object, boolean)</code></a></li> |
