Method Detail

getPrimitiveWritableObject

public org.apache.hadoop.hive.serde2.io.HiveDecimalWritable getPrimitiveWritableObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Return the data in an instance of primitive writable Object. If the Object is already a primitive writable Object, just return o.

Specified by:

getPrimitiveWritableObject in interface HiveDecimalObjectInspector

Specified by:

getPrimitiveWritableObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveWritableObject in class AbstractPrimitiveWritableObjectInspector

getPrimitiveJavaObject

public org.apache.hadoop.hive.common.type.HiveDecimal getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface HiveDecimalObjectInspector

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

copyObject

public Object copyObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get a copy of the Object in the same class, so the return value can be stored independently of the parameter. If the Object is a Primitive Java Object, we just return the parameter since Primitive Java Object is immutable.

Specified by:

copyObject in interface PrimitiveObjectInspector

set

public Object set(Object o,
                  byte[] bytes,
                  int scale)

Specified by:

set in interface SettableHiveDecimalObjectInspector

set

public Object set(Object o,
                  org.apache.hadoop.hive.common.type.HiveDecimal t)

Specified by:

set

public Object set(Object o,
                  org.apache.hadoop.hive.serde2.io.HiveDecimalWritable t)

Specified by:

create

public Object create(byte[] bytes,
                     int scale)

Specified by:

create in interface SettableHiveDecimalObjectInspector

create

public Object create(org.apache.hadoop.hive.common.type.HiveDecimal t)
