Using User Metadata on a Riak Object

UserMetadata.java

		// Build Test Data
		IRiakObject cat = RiakObjectBuilder.newBuilder("Pets-Template", "Cat").
			withValue("{\"sound\":\"Meow\",\"legs\":4}").
			build();
		rc.store(cat);

		// Build User Metadata Map
		Map<String, String> usermeta = new HashMap<String, String>();
		usermeta.put("parentLinkBucket", "Pets-Template");
		usermeta.put("parentLinkKey", "Cat");

		// Store Object 
		IRiakObject stellaToStore = RiakObjectBuilder.newBuilder("Pets", "Stella").
				withValue("{\"owner\":\"Charlie Voiselle\"}").
				withUsermeta(usermeta).
				build();	
		rc.store(stellaToStore);
		
		// Fetch Object
		IRiakObject pet = rc.fetch("Pets", "Stella").getRiakObjects()[0];
		IRiakObject petTemplate = rc.fetch(
				pet.getUsermeta("parentlinkbucket"), 
				pet.getUsermeta("parentlinkkey")).getRiakObjects()[0];
		System.out.printf("Pet: %s%nTemplate: %s", pet.getValueAsString(), 
				petTemplate.getValueAsString());
