Class LazyObjectInspectorFactory
java.lang.Object
org.apache.hadoop.hive.serde2.lazy.objectinspector.LazyObjectInspectorFactory
public final class LazyObjectInspectorFactory
- 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 ObjectInspectors do not have an
internal state - so ObjectInspectors with the same construction parameters
should result in exactly the same ObjectInspector.
