Constructor Detail

LazyHBaseRow

public LazyHBaseRow(LazySimpleStructObjectInspector oi,
            HBaseSerDeParameters serdeParams)

Construct a LazyHBaseRow object with the ObjectInspector.

Method Detail

init

public void init(org.apache.hadoop.hbase.client.Result r)

Set the HBase row data(a Result writable) for this LazyStruct.

See Also:

init(org.apache.hadoop.hbase.client.Result)

createLazyField

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

Overrides:

createLazyField in class LazyStruct

Throws:

SerDeException

getField

public Object getField(int fieldID)

Get one field out of the HBase row. 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 uses the Object instead of going through Object PrimitiveObjectInspector.get(Object).

Specified by:

getField in interface StructObject

Overrides:

getField in class LazyStruct

Parameters:

fieldID - The field ID

Returns:

The field as a LazyObject

getFieldsAsList

public ArrayList<Object> getFieldsAsList()

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.

getObject

public Object getObject()

Description copied from class: LazyObject

Returns the primitive object represented by this LazyObject. This is useful because it can make sure we have "null" for null objects.

Specified by:

getObject in interface LazyObjectBase

Overrides:

getObject in class LazyObject<LazySimpleStructObjectInspector>
