Class JacksonJsonpParser

java.lang.Object
co.elastic.clients.json.jackson.JacksonJsonpParser
All Implemented Interfaces:
BufferingJsonParser, LookAheadJsonParser, jakarta.json.stream.JsonParser, Closeable, AutoCloseable
public class JacksonJsonpParser extends Object implements LookAheadJsonParser, BufferingJsonParser
A JSONP parser implementation on top of Jackson.

Warning: this implementation isn't fully compliant with the JSONP specification: calling hasNext() moves forward the underlying Jackson parser as Jackson doesn't provide an equivalent method. This means no value getter method (e.g. getInt() or getString() should be called until the next call to next(). Such calls will throw an IllegalStateException.
