Method Detail

getPrimitiveWritableObject

public T 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.

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.
