Class ArrayWritableObjectInspector

java.lang.Object

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

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

org.apache.hadoop.hive.ql.io.parquet.serde.ArrayWritableObjectInspector

All Implemented Interfaces:

Cloneable, ObjectInspector

public class ArrayWritableObjectInspector
extends SettableStructObjectInspector

The ArrayWritableObjectInspector will inspect an ArrayWritable, considering it as a Hive struct.
It can also inspect a List if Hive decides to inspect the result of an inspection.

Method Detail

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.

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.

getAllStructFieldRefs

public List<? extends StructField> getAllStructFieldRefs()

Description copied from class: StructObjectInspector

Returns all the fields.

Specified by:

getAllStructFieldRefs in class StructObjectInspector

getStructFieldData

public Object getStructFieldData(Object data,
                        StructField fieldRef)

Description copied from class: StructObjectInspector

returns null for data = null.

Specified by:

getStructFieldData in class StructObjectInspector

getStructFieldRef

public StructField getStructFieldRef(String name)

Description copied from class: StructObjectInspector

Look up a field.

Specified by:

getStructFieldRef in class StructObjectInspector

getStructFieldsDataAsList

public List<Object> getStructFieldsDataAsList(Object data)

Description copied from class: StructObjectInspector

returns null for data = null.

Specified by:

getStructFieldsDataAsList in class StructObjectInspector

create

public Object create()

Description copied from class: SettableStructObjectInspector

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

Specified by:

create in class SettableStructObjectInspector

setStructFieldData

                        StructField field,
                        Object fieldValue)

Description copied from class: SettableStructObjectInspector

Modify the value of a field. Returns the struct.

Specified by:

setStructFieldData in class SettableStructObjectInspector

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
