Class ThriftUnionObjectInspector

java.lang.Object

org.apache.hadoop.hive.serde2.objectinspector.StructObjectInspector

org.apache.hadoop.hive.serde2.objectinspector.SettableStructObjectInspector

org.apache.hadoop.hive.serde2.objectinspector.ReflectionStructObjectInspector

org.apache.hadoop.hive.serde2.objectinspector.ThriftUnionObjectInspector

All Implemented Interfaces:

Cloneable, ObjectInspector, UnionObjectInspector

public class ThriftUnionObjectInspector
extends ReflectionStructObjectInspector
implements UnionObjectInspector

Always use the ObjectInspectorFactory to create new ObjectInspector objects, instead of directly creating an instance of this class.

Method Detail

shouldIgnoreField

public boolean shouldIgnoreField(String name)

Overrides:

shouldIgnoreField in class ReflectionStructObjectInspector

getObjectInspectors

public List<ObjectInspector> getObjectInspectors()

Description copied from interface: UnionObjectInspector

Returns the array of ObjectInspectors that are for each of the tags.

Specified by:

getObjectInspectors in interface UnionObjectInspector

getTag

public byte getTag(Object o)

Description copied from interface: UnionObjectInspector

Return the tag of the object.

Specified by:

getTag in interface UnionObjectInspector

getField

public Object getField(Object o)

Description copied from interface: UnionObjectInspector

Return the field based on the tag associated with the Object.

Specified by:

getField in interface UnionObjectInspector

init

protected void init(Class<?> objectClass,
        ObjectInspectorFactory.ObjectInspectorOptions options)

This method is only intended to be used by Utilities class in this package. The reason that this method is not recursive by itself is because we want to allow recursive types.

Overrides:

init in class ReflectionStructObjectInspector

getCategory

public ObjectInspector.Category getCategory()

Description copied from interface: ObjectInspector

An ObjectInspector must inherit from one of the following interfaces if getCategory() returns: PRIMITIVE: PrimitiveObjectInspector LIST: ListObjectInspector MAP: MapObjectInspector STRUCT: StructObjectInspector.

Specified by:

getCategory in interface ObjectInspector

Overrides:

getCategory in class ReflectionStructObjectInspector

getAllStructFieldRefs

public List<? extends StructField> getAllStructFieldRefs()

Description copied from class: StructObjectInspector

Returns all the fields.

Overrides:

getAllStructFieldRefs in class ReflectionStructObjectInspector

getTypeName

public String getTypeName()

Description copied from interface: ObjectInspector

Returns the name of the data type that is inspected by this ObjectInspector. This is used to display the type information to the user. For primitive types, the type name is standardized. For other types, the type name can be something like "list", "map", java class names, or user-defined type names similar to typedef.

Specified by:

getTypeName in interface ObjectInspector

Overrides:

getTypeName in class ReflectionStructObjectInspector

create

public Object create()

Description copied from class: SettableStructObjectInspector

Create a struct which is not null, but all its fields are null.

Overrides:

create in class ReflectionStructObjectInspector
