Most mutators, however, need to be accessed through 137 specific sub-classes (such as <code>ObjectNode</code> 138 and <code>ArrayNode</code>). 139 This seems sensible because proper type 140 information is generally available when building or modifying 141 trees, but less often when reading a tree (newly built from 142 parsed JSON content). 143<p> 144 Actual concrete sub-classes can be found from package 145 <a href="../../../../com/fasterxml/jackson/databind/node/package-summary.html"><code>com.fasterxml.jackson.databind.node</code></a>. 146<p> 147 Note that it is possible to "read" from nodes, using 148 method <a href="http://fasterxml.github.com/jackson-core/javadoc/2.9/com/fasterxml/jackson/core/TreeNode.html?is-external=true#traverse-com.fasterxml.jackson.core.ObjectCodec-" title="class or interface in com.fasterxml.jackson.core"><code>TreeNode.traverse(ObjectCodec)</code></a>, which will result in 149 a <a href="http://fasterxml.github.com/jackson-core/javadoc/2.9/com/fasterxml/jackson/core/JsonParser.html?is-external=true" title="class or interface in com.fasterxml.jackson.core"><code>JsonParser</code></a> being constructed.
