title: Parse JSON with GSON without a model
body: <p>Suppose you have a JSON object:</p>
  
  <pre><code>{
    "mappings": {
      "s54dsf45fzd324": "135sdq13sod1tt3",
      "21sm24dsfp2ds2": "123sd56f4gt4ju4"
    }
  }
  </code></pre>
  
  <p>The only thing you know about the mappings object is that it maps strings to strings, but you do not know the key values.</p>
  
  <p>Is it possible to parse this object with GSON and cycle through the key/value pairs?</p>
