Package com.fasterxml.jackson.databind Description
</H2>
<P>
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
<A HREF="../../../../com/fasterxml/jackson/databind/ObjectMapper.html" title="class in com.fasterxml.jackson.databind"><CODE>ObjectMapper</CODE></A> class, as well
as convenience methods included in
<A HREF="http://fasterxml.github.com/jackson-core/javadoc/2.1.0/com/fasterxml/jackson/core/JsonParser.html?is-external=true" title="class or interface in com.fasterxml.jackson.core"><CODE>JsonParser</CODE></A>
<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 <A HREF="../../../../com/fasterxml/jackson/databind/JsonNode.html" title="class in com.fasterxml.jackson.databind"><CODE>JsonNode</CODE></A>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 <code>JsonNode</code> 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.
