        Read and return raw json content as a String.
      • location

        String location()
        Return the current location. This is typically used when reporting errors.

        Skip the next value.
      • unmappedField

        void unmappedField​(String fieldName)
        Reading json with an unmapped field, throw an Exception if failOnUnmapped is true.
      • streamArray

        default JsonReader streamArray​(boolean streamArray)
        Explicitly state if the streaming content contains ARRAY '[' and ']' tokens.

        The builtin avaje-jsonb parser detects this automatically. Effectively we only need to set this when we are using the Jackson core parser.

        
        
          try (JsonReader reader = jsonb.reader(arrayJson)) {
            // content contains ARRAY '[' and ']' tokens, use streamArray(true)
            Stream<MyBasic> asStream = type.stream(reader.streamArray(true));
            asStream.forEach(...);
          }
        
         
        Parameters:
        streamArray - When true the content is expected to contain ARRAY '[' and ']' tokens.
