public class TreeTraversingParser
extends com.fasterxml.jackson.core.base.ParserMinimalBase
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.Modifier and Type | Field and Description |
---|---|
protected boolean |
_closed
Flag that indicates whether parser is closed or not.
|
protected com.fasterxml.jackson.core.JsonToken |
_nextToken
Sometimes parser needs to buffer a single look-ahead token; if so,
it'll be stored here.
|
protected com.fasterxml.jackson.databind.node.NodeCursor |
_nodeCursor
Traversal context within tree
|
protected com.fasterxml.jackson.core.ObjectCodec |
_objectCodec |
protected boolean |
_startContainer
Flag needed to handle recursion into contents of child
Array/Object nodes.
