Class TreeTraversingParser

java.lang.Object
com.fasterxml.jackson.core.JsonParser
com.fasterxml.jackson.core.base.ParserMinimalBase
com.fasterxml.jackson.databind.node.TreeTraversingParser
All Implemented Interfaces:
com.fasterxml.jackson.core.Versioned, Closeable, AutoCloseable
public class TreeTraversingParser extends com.fasterxml.jackson.core.base.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.
