public ColumnarStructBase(ObjectInspector oi,
                          List<Integer> notSkippedColumnIDs)

Method Detail

getField

public Object getField(int fieldID)

Get one field out of the struct. If the field is a primitive field, return the actual object. Otherwise return the LazyObject. This is because PrimitiveObjectInspector does not have control over the object used by the user - the user simply directly use the Object instead of going through Object PrimitiveObjectInspector.get(Object). NOTE: separator and nullSequence has to be the same each time this method is called. These two parameters are used only once to parse each record.

Parameters:

fieldID - The field ID

Returns:

The field as a LazyObject

init

public void init(BytesRefArrayWritable cols)

getFieldsAsList

public ArrayList<Object> getFieldsAsList()

Get the values of the fields as an ArrayList.

Returns:

The values of the fields as an ArrayList.

getRawDataSerializedSize

public long getRawDataSerializedSize()

Description copied from interface: SerDeStatsStruct

Rerurns the serialized size of the object.
