 If you want to **optionally** route to 1 or more edges (or optionally terminate), you can use the [`addConditionalEdges`] method. This method accepts the name of a node and a **Functional Interface** ([`AsyncEdgeAction`]) that will be used as " routing function" to call after that node is executed:
 
 ```java
-import static org.bsc.langgraph4j.utils.CollectionsUtils.mapOf;

-graph.addConditionalEdges("nodeA", routingFunction, mapOf( "first": "nodeB", "second": "nodeC" ) );
+graph.addConditionalEdges("nodeA", routingFunction, Map.of( "first": "nodeB", "second": "nodeC" ) );
 ```
 
 Similar to nodes, the `routingFunction` accept the current `state` of the graph and return a string value.
