All Implemented Interfaces:

SerDeStatsStruct

public class LazyHBaseRow
extends LazyStruct

LazyObject for storing an HBase row. The field of an HBase row can be primitive or non-primitive.

Constructor Summary

LazyHBaseRow(LazySimpleStructObjectInspector oi)
Construct a LazyHBaseRow object with the ObjectInspector.

Method Summary

Object	getField(int fieldID) Get one field out of the HBase row.
ArrayList<Object>	getFieldsAsList() Get the values of the fields as an ArrayList.
Object	getObject()
void	init(org.apache.hadoop.hbase.client.Result r, List<org.apache.hadoop.hive.hbase.HBaseSerDe.ColumnMapping> columnsMapping) Set the HBase row data(a Result writable) for this LazyStruct.
void	init(org.apache.hadoop.hbase.client.Result r, List<org.apache.hadoop.hive.hbase.HBaseSerDe.ColumnMapping> columnsMapping, Object compositeKeyObj) Set the HBase row data(a Result writable) for this LazyStruct.

Constructor Detail

LazyHBaseRow

public LazyHBaseRow(LazySimpleStructObjectInspector oi)

Construct a LazyHBaseRow object with the ObjectInspector.

Method Detail

init

public void init(org.apache.hadoop.hbase.client.Result r,
                 List<org.apache.hadoop.hive.hbase.HBaseSerDe.ColumnMapping> columnsMapping)

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

See Also:

LazyHBaseRow#init(Result)

init

public void init(org.apache.hadoop.hbase.client.Result r,
                 List<org.apache.hadoop.hive.hbase.HBaseSerDe.ColumnMapping> columnsMapping,
                 Object compositeKeyObj)

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

Parameters:

compositeKeyClass - custom implementation to interpret the composite key

See Also:

LazyHBaseRow#init(Result)

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).

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.

Overrides:

getFieldsAsList in class LazyStruct

Returns:

The values of the fields as an ArrayList.

getObject

public Object getObject()

Overrides:

getObject in class LazyStruct
