Enum Constant Detail

ENCRYPTION_ALGORITHM

public static final FileCryptoMetaData._Fields ENCRYPTION_ALGORITHM

Encryption algorithm. This field is only used for files with encrypted footer. Files with plaintext footer store algorithm id inside footer (FileMetaData structure).

KEY_METADATA

public static final FileCryptoMetaData._Fields KEY_METADATA

Retrieval metadata of key used for encryption of footer, and (possibly) columns *

Method Detail

values

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

Returns:

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

valueOf

public static FileCryptoMetaData._Fields 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

findByThriftId

public static FileCryptoMetaData._Fields findByThriftId(int fieldId)

Find the _Fields constant that matches fieldId, or null if its not found.

findByThriftIdOrThrow

public static FileCryptoMetaData._Fields findByThriftIdOrThrow(int fieldId)

Find the _Fields constant that matches fieldId, throwing an exception if it is not found.

findByName

public static FileCryptoMetaData._Fields findByName(String name)

Find the _Fields constant that matches name, or null if its not found.
