## Class JsonNodeFactory

- java.lang.Object
- - org.codehaus.jackson.node.JsonNodeFactory

-     public class JsonNodeFactory
      extends Object

  Base class that specifies methods for getting access to Node instances (newly constructed, or shared, depending on type), as well as basic implementation of the methods. Designed to be sub-classed if extended functionality (additions to behavior of node types, mostly) is needed.

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static JsonNodeFactory` | `instance` Default singleton instance that construct "standard" node instances: given that this class is stateless, a globally shared singleton can be used.
