convenience methods included in 485<code>JsonParser</code> 486<p> 487Object mapper will convert Json content to ant from 488basic Java wrapper types (Integer, Boolean, Double), 489Collection types (List, Map), Java Beans, 490Strings and nulls. 491<p> 492Tree 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 493from JSON content (and writes such trees as JSON), 494similar to how DOM model works with XML. 495Main benefits over Object mapping are: 496<ul> 497 <li>No null checks are needed (dummy 498nodes are created as necessary to represent "missing" Object fields 499and Array elements) 500 </li> 501 <li>No type casts are usually needed: all public access methods are defined 502in basic <code>JsonNode</code> class, and when "incompatible" method (such as Array 503element access on, say, Boolean node) is used, returned node is 504virtual "missing" node. 505 </li> 506</ul> 507Because of its dynamic nature, Tree mapping is often convenient 508for basic path access and tree navigation, where structure of 509the resulting tree is known in advance.</div> 510</div> 511<!-- ======= START OF BOTTOM NAVBAR ====== --> 512<div class="bottomNav"><a name="navbar_bottom"> 513<!-- --> 514</a><a href="#skip-navbar_bottom" title="Skip navigation
