Class ObjectInspectorFactory
java.lang.Object
org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorFactory
public final 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.
