TreeTraversingParser (jackson-databind 2.13.0 API)

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, AutoCloseable
```
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.
