Class TreeTraversingParser

java.lang.Object

tools.jackson.core.JsonParser

tools.jackson.core.base.ParserMinimalBase

tools.jackson.databind.node.TreeTraversingParser

All Implemented Interfaces:

Closeable, AutoCloseable, Versioned

public class TreeTraversingParser
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.

Since:

3.0

_nodeCursor

protected tools.jackson.databind.node.NodeCursor _nodeCursor

Traversal context within tree

_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.
