Class PositionChecker

java.lang.Object

org.eclipse.yasson.internal.deserializer.PositionChecker

All Implemented Interfaces:

ModelDeserializer<jakarta.json.stream.JsonParser>

public class PositionChecker
extends Object
implements ModelDeserializer<jakarta.json.stream.JsonParser>

JSON document position checker.
Checks whether json parser is in expected state. If not it will try to skip to the next event, since if user defined components are involved, it is possible to expect incorrect states in terms of the last expected events. If this checker is still not in expected state, an exception is thrown.
