Snakeyaml to convert yaml to pojo

I want to load a list of POJO from my yaml file. Is it possible for me to do that using snake yaml?

my yaml file looks something like this -- 

- pty1:val1
  pty2:val2

- pty1:val1
  pty2:val2

And my pojo - 

class pojo {
  String pty1;
  String pty2;
}

Snakeyaml documentation does say to use loadAs() but that loads a single element. Can I load list of such elements with automatic type binding?

Thanks!

I've started using Jackson's YAML format plugin for serializing and deserializing YAML. Quite friendly.

One way to achieve this is to create a class that contains a list of POJO.

class POJOList {
    List<pojo> pojoList;
    public POJOList(List<pojo> pojoList) {
        this.pojoList = pojoList;
    }
}

You can then read the yaml file under the resources folder as:

InputStream in = ClassLoader.getResourceAsStream("pojolist.yaml");
POJOList pojoList = yaml.loadAs(in, POJOList.class);
