| /** |
| Contains basic mapper (conversion) functionality that |
| allows for converting between regular streaming json content and |
| Java objects (beans or Tree Model: support for both is via |
| {@link org.codehaus.jackson.map.ObjectMapper} class, as well |
| as convenience methods included in |
| {@link org.codehaus.jackson.JsonParser} |
| <p> |
| Object mapper will convert Json content to ant from |
| basic Java wrapper types (Integer, Boolean, Double), |
| Collection types (List, Map), Java Beans, |
| Strings and nulls. |
| <p> |
| Tree mapper builds dynamically typed tree of <code>JsonNode</code>s |
| from Json content (and writes such trees as Json), |
| similar to how DOM model works with xml. |
| Main benefits over Object mapping are: |
| <ul> |
| <li>No null checks are needed (dummy |
| nodes are created as necessary to represent "missing" Object fields |
| and Array elements) |
| </li> |
| <li>No type casts are usually needed: all public access methods are defined |
| in basic JsonNode class, and when "incompatible" method (such as Array |
| element access on, say, Boolean node) is used, returned node is |
| virtual "missing" node. |
| </li> |
| </ul> |
| Because of its dynamic nature, Tree mapping is often convenient |
| for basic path access and tree navigation, where structure of |
| the resulting tree is known in advance. |
