Method Detail

getPrimitiveJavaObject

public HiveChar getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface HiveCharObjectInspector

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

getPrimitiveWritableObject

public HiveCharWritable 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 HiveCharObjectInspector

Specified by:

getPrimitiveWritableObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveWritableObject in class AbstractPrimitiveWritableObjectInspector

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,
                  HiveChar value)

Specified by:

set in interface SettableHiveCharObjectInspector

set

public Object set(Object o,
                  String value)

Specified by:

set in interface SettableHiveCharObjectInspector

create

public Object create(HiveChar value)

Specified by:

create in interface SettableHiveCharObjectInspector

getMaxLength

public int getMaxLength()
