Class 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.

      Fields 
      Modifier and Type Field 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.
