title: Generic JSON object conversion
body: <p>I am de-serializing a JSON object with the <a href="http://jackson.codehaus.org/0.9.9/javadoc/org/codehaus/jackson/map/ObjectMapper.html" rel="nofollow noreferrer">ObjectMapper</a> class in java.
  I am getting objects of different types (? extends Something) and wanted to know if there is any way to de-serialize them in some generic way.
  The <a href="http://jackson.codehaus.org/0.9.9/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(java.lang.String,%20java.lang.Class)" rel="nofollow noreferrer">readValue</a> method gets some Class type object of the type of the output object so it is somehow strongly typed.</p>
