public class TreeTraversingParser extends 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.JsonParser.Feature, JsonParser.NumberType
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 boolean |
_startContainer
Flag needed to handle recursion into contents of child
Array/Object nodes.
