JrsTreeTraversingParser (jackson-jr-all 2.11.0 API)

java.lang.Object
- com.fasterxml.jackson.core.JsonParser
- - com.fasterxml.jackson.core.base.ParserMinimalBase
  - - com.fasterxml.jackson.jr.stree.util.JrsTreeTraversingParser

All Implemented Interfaces:

Versioned, Closeable, AutoCloseable
```
public class JrsTreeTraversingParser
extends ParserMinimalBase
```
Facade over JrsValue 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.

Fields
Modifier and Type	Field and Description
`protected boolean`	`_closed` Flag that indicates whether parser is closed or not.
`protected JsonToken`	`_nextToken` Sometimes parser needs to buffer a single look-ahead token; if so, it'll be stored here.
`protected com.fasterxml.jackson.jr.stree.util.JrsValueCursor`	`_nodeCursor` Traversal context within tree
`protected ObjectCodec`	`_objectCodec` Optional codec, to allow chaining.
`protected boolean`	`_startContainer` Flag needed to handle recursion into contents of child Array/Object nodes.

protected com.fasterxml.jackson.jr.stree.util.JrsValueCursor _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.
