JarCastingYAML API 
A Jackson-like API to create YAML nodes (based on SnakeYAML).
Example Usage
Maven
Add this to your dependencies:
<dependency>
<groupId>com.github.autermann</groupId>
<artifactId>yaml</artifactId>
<version>1.0.3</version>
</dependency>
Note: Requires JDK 1.8 or higher
Creating nodes
YamlNodeFactory factory = YamlNodeFactory.createDefault();
YamlMapNode mnode = factory.orderedMapNode();
mnode.put("hello", "world")
.put("key", true)
.put("integer", 2)
.put("double", 42.0d)
.put("time", DateTime.now(DateTimeZone.UTC));
mnode.putSequence("message")
.add("this").add("is").add("snakeyaml-api");
mnode.putPairs("pairs")
.put("pair1", "pair1")
.put("pair1", "pair1")
.put("pair2", "pair2");
byte[] bytes = new byte[240];
new Random().nextBytes(bytes);
mnode.put("binary", bytes);
mnode.dump(System.out);
!!omap
hello: world
key: true
integer: 2
double: 42.0
time: 2013-11-06T02:33:08.701Z
message: [this, is, snakeyaml-api]
pairs: !!pairs
pair1: pair1
pair1: pair1
pair2: pair2
binary: !!binary |-

Reading Nodes
YamlNode loaded = new Yaml().load(/*...*/);
if (loaded.isMapping()) {
YamlMappingNode node = loaded.asMapping();
node.path("hello").textValue(); // world
node.path("binary").binaryValue(); // byte[240]
node.path("message").asSequence().get(2); //snakeyaml-api
}
Anchors and Aliases
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: *id001
YamlNode node = YAML.load(/* ... */);
System.out.println(node.path("a") == node.path("b")); // == true
