@Tags(value={"json","tree","record","reader","parser"}) @CapabilityDescription(value="Parses JSON into individual Record objects. While the reader expects each record to be well-formed JSON, the content of a FlowFile may consist of many records, each as a well-formed JSON array or JSON object with optional whitespace between them, such as the common \'JSON-per-line\' format. If an array is encountered, each element in that array will be treated as a separate record. If the schema that is configured contains a field that is not present in the JSON, a null value will be used. If the JSON contains a field that is not present in the schema, that field will be skipped. See the Usage of the Controller Service for more information and examples.") @SeeAlso(value=JsonPathReader.class) public class JsonTreeReader extends SchemaRegistryService implements RecordReaderFactory
