Enum RecordIdentifier.Field

java.lang.Object

java.lang.Enum<RecordIdentifier.Field>

org.apache.hadoop.hive.ql.io.RecordIdentifier.Field

All Implemented Interfaces:

Serializable, Comparable<RecordIdentifier.Field>

Enclosing class:

RecordIdentifier

public static enum RecordIdentifier.Field
extends Enum<RecordIdentifier.Field>

This is in support of VirtualColumn.ROWID Contains metadata about each field in RecordIdentifier that needs to be part of ROWID which is represented as a struct RecordIdentifier.StructInfo. Each field of RecordIdentifier which should be part of ROWID should be in this enum... which really means that it should be part of VirtualColumn (so make a subclass for rowid).

Method Detail

values

public static RecordIdentifier.Field[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RecordIdentifier.Field c : RecordIdentifier.Field.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RecordIdentifier.Field valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
