Method Detail

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.


init

protected void init(List<String> structFieldNames,
                    List<ObjectInspector> structFieldObjectInspectors)

getCategory

public final 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.


getStructFieldRef

public StructField getStructFieldRef(String fieldName)
Description copied from class: StructObjectInspector
Look up a field.

Specified by:
getStructFieldRef in class StructObjectInspector

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

getStructFieldsDataAsList

public List<Object> getStructFieldsDataAsList(Object data)
Description copied from class: StructObjectInspector
returns null for data = null.

Specified by:
