Method Detail

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

getPrimitiveJavaObject

public byte[] getPrimitiveJavaObject(Object o)
Description copied from interface: PrimitiveObjectInspector
Get the Java Primitive object.

Specified by:
getPrimitiveJavaObject in interface BinaryObjectInspector
Specified by:
getPrimitiveJavaObject in interface PrimitiveObjectInspector

getPrimitiveWritableObject

public org.apache.hadoop.io.BytesWritable 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 BinaryObjectInspector
Specified by:
getPrimitiveWritableObject in interface PrimitiveObjectInspector
Overrides:
getPrimitiveWritableObject in class AbstractPrimitiveLazyObjectInspector<org.apache.hadoop.io.BytesWritable>
