Enum ConvertedType

java.lang.Object

java.lang.Enum<ConvertedType>

parquet.format.ConvertedType

All Implemented Interfaces:

Serializable, Comparable<ConvertedType>, org.apache.thrift.TEnum

public enum ConvertedType
extends Enum<ConvertedType>
implements org.apache.thrift.TEnum

Common types used by frameworks(e.g. hive, pig) using parquet. This helps map between types in those frameworks to the base types in parquet. This is only metadata and not needed to read or write the data.

Enum Constant Detail

UTF8

public static final ConvertedType UTF8

a BYTE_ARRAY actually contains UTF8 encoded chars

MAP

public static final ConvertedType MAP

a map is converted as an optional field containing a repeated key/value pair

MAP_KEY_VALUE

public static final ConvertedType MAP_KEY_VALUE

a key/value pair is converted into a group of two fields

LIST

public static final ConvertedType LIST

a list is converted into an optional field containing a repeated field for its values

Method Detail

values

public static ConvertedType[] 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 (ConvertedType c : ConvertedType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ConvertedType 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

getValue

public int getValue()

Get the integer value of this enum value, as defined in the Thrift IDL.

Specified by:

getValue in interface org.apache.thrift.TEnum

findByValue

public static ConvertedType findByValue(int value)

Find a the enum type by its integer value, as defined in the Thrift IDL.

Returns:

null if the value is not found.
