Method Detail

get

public long get(java.lang.Object o)

Description copied from interface: LongObjectInspector

Get the long data.

Specified by:

get in interface LongObjectInspector

copyObject

public java.lang.Object copyObject(java.lang.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

getPrimitiveJavaObject

public java.lang.Object getPrimitiveJavaObject(java.lang.Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector
