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:: Versioned, Closeable

public class TreeTraversingParser
extends ParserMinimalBase
extends 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.

Field Detail

_objectCodec

protected ObjectCodec _objectCodec

_nodeCursor

protected com.fasterxml.jackson.databind.node.NodeCursor _nodeCursor

Traversal context within tree

_nextToken

protected JsonToken _nextToken

Sometimes parser needs to buffer a single look-ahead token; if so, it'll be stored here. This is currently used for handling

_startContainer

protected boolean _startContainer

Flag needed to handle recursion into contents of child Array/Object nodes.

_closed

protected boolean _closed

Flag that indicates whether parser is closed or not. Gets set when parser is either closed by explicit call (close()) or when end-of-input is reached.
