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.
