Examples of StandardStructObjectInspector

org.apache.hadoop.hive.serde2.objectinspector.StandardStructObjectInspector
ListStructObjectInspector works on struct data that is stored as a Java List or Java Array object. Basically, the fields are stored sequentially in the List object. The names of the struct fields and the internal structure of the struct fields are specified in the ctor of the StructObjectInspector. Always use the ObjectInspectorFactory to create new ObjectInspector objects, instead of directly creating an instance of this class.

    super.initializeOp(hconf);

  public void processOp(Object row, int tag) throws HiveException {
    // The UDTF expects arguments in an object[]
    StandardStructObjectInspector soi =
      (StandardStructObjectInspector) inputObjInspectors[tag];
    List<? extends StructField> fields = soi.getAllStructFieldRefs();


    for (int i=0; i<fields.size(); i++) {
      objToSendToUDTF[i] = soi.getStructFieldData(row, fields.get(i));
    }


    conf.getGenericUDTF().process(objToSendToUDTF);
