Class PrimitiveObjectInspectorFactory

java.lang.Object

org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory

public final class PrimitiveObjectInspectorFactory
extends Object

PrimitiveObjectInspectorFactory is the primary way to create new PrimitiveObjectInspector instances. 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.
