}As long they are not recursive, they are supported:
YamlMapNode a = factory.mapNode().put("value", true);
YamlMapNode root = factory.orderedMapNode().put("a", a).put("b", a);
System.out.println(root.dump());!!omap
a: &id001
value: true
b: *id001YamlNode node = YAML.load(/* ... */);
System.out.println(node.path("a") == node.path("b")); // == trueThe project is licensed under the Apache License, Version 2.0
