Class ObjectInspectorFactory
java.lang.Object
org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorFactory
public class ObjectInspectorFactory
- extends Object
ObjectInspectorFactory is the primary way to create new ObjectInspector instances.
SerDe classes should call the static functions in this library to create an ObjectInspector
to return to the caller of SerDe2.getObjectInspector().
The reason of having caches here is that ObjectInspector is because ObjectInspectors do
not have an internal state - so ObjectInspectors with the same construction parameters should
result in exactly the same ObjectInspector.
