Examples of org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.copyObject()

org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector.copyObject()
Get a copy of the Object in the same class, so the return value can be stored independently of the parameter. If the Object is a Primitive Java Object, we just return the parameter since Primitive Java Object is immutable.


        DateTimeOption option = new DateTimeOption(new DateTime(2014, 7, 1, 12, 5, 59));
        String value = "2014-07-01 12:05:59";


        assertThat(inspector.copyObject(option), is((Object) option));
        assertThat(inspector.copyObject(option), is(not(sameInstance((Object) option))));
        assertThat(inspector.copyObject(null), is(nullValue()));
        assertThat(inspector.getPrimitiveJavaObject(option), is(value));
        assertThat(inspector.getPrimitiveJavaObject(null), is(nullValue()));
        assertThat(inspector.getPrimitiveWritableObject(option), is(new Text(value)));
        assertThat(inspector.getPrimitiveWritableObject(null), is(nullValue()));
