Most mutators, however, need to be accessed through 119 specific sub-classes (such as <code>ObjectNode</code> 120 and <code>ArrayNode</code>). 121 This seems sensible because proper type 122 information is generally available when building or modifying 123 trees, but less often when reading a tree (newly built from 124 parsed JSON content). 125<p> 126 Actual concrete sub-classes can be found from package 127 <a href="../../../../com/fasterxml/jackson/databind/node/package-summary.html"><code>com.fasterxml.jackson.databind.node</code></a>. 128<p> 129 Note that it is possible to "read" from nodes, using 130 method <code>TreeNode.traverse(ObjectCodec)</code>, which will result in 131 a <code>JsonParser</code> being constructed.
