| JSON Details |
| |
| <p> |
| Juneau supports converting arbitrary POJOs to and from JSON using ultra-efficient serializers and parsers. |
| The JSON serializer converts POJOs directly to JSON without the need for intermediate DOM objects using a |
| highly-efficient state machine. |
| Likewise, the JSON parser creates POJOs directly from JSON without the need for intermediate DOM objects. |
| </p> |
| <p> |
| The following example shows JSON for a typical bean: |
