@Tags(value={"yaml","tree","record","reader","parser"}) @CapabilityDescription(value="Parses YAML into individual Record objects. While the reader expects each record to be well-formed YAML, the content of a FlowFile may consist of many records, each as a well-formed YAML array or YAML object. 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 YAML, a null value will be used. If the YAML contains a field that is not present in the schema, that field will be skipped. Please note this controller service does not support resolving the use of YAML aliases. Any alias present will be treated as a string. See the Usage of the Controller Service for more information and examples.") public class YamlTreeReader extends JsonTreeReader
