Method Detail

init

        List<ColumnMapping> columnMappings,
        AccumuloRowIdFactory rowIdFactory)

getField

public Object getField(int id)

Description copied from class: LazyStruct

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).

Specified by:

getField in interface StructObject

Overrides:

getField in class LazyStruct

Parameters:

id - The field ID

Returns:

The field as a LazyObject

getFieldsAsList

public ArrayList<Object> getFieldsAsList()

Description copied from class: LazyStruct

Get the values of the fields as an ArrayList.

Specified by:

getFieldsAsList in interface StructObject

Overrides:

getFieldsAsList in class LazyStruct

Returns:

The values of the fields as an ArrayList.

createLazyField

protected LazyObjectBase createLazyField(int fieldID,
                             StructField fieldRef)
                                  throws SerDeException

Overrides:

createLazyField in class LazyStruct

Throws:

SerDeException
