Methods

Modifier and Type	Method and Description
Object	copyObject(Object o) Get a copy of the Object in the same class, so the return value can be stored independently of the parameter.
Object	getPrimitiveJavaObject(Object o) Get the Java Primitive object.
boolean	preferWritable() Whether the ObjectInspector prefers to return a Primitive Writable Object instead of a Primitive Java Object.

Method Detail

getPrimitiveJavaObject

public Object getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

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.

preferWritable

public boolean preferWritable()

Description copied from interface: PrimitiveObjectInspector

Whether the ObjectInspector prefers to return a Primitive Writable Object instead of a Primitive Java Object. This can be useful for determining the most efficient way to getting data out of the Object.
