Class TreeTraversingParser

  • java.lang.Object
    • com.fasterxml.jackson.core.JsonParser
      • com.fasterxml.jackson.core.base.ParserMinimalBase
        • com.fasterxml.jackson.databind.node.TreeTraversingParser
  • All Implemented Interfaces:
    com.fasterxml.jackson.core.Versioned, Closeable, AutoCloseable

    public class TreeTraversingParser
extends com.fasterxml.jackson.core.base.ParserMinimalBase
    Facade over JsonNode that implements JsonParser to allow accessing contents of JSON tree in alternate form (stream of tokens). Useful when a streaming source is expected by code, such as data binding functionality.
