Enum BookKeeper.DigestType

java.lang.Object

java.lang.Enum<BookKeeper.DigestType>

org.apache.bookkeeper.client.BookKeeper.DigestType

All Implemented Interfaces:

Serializable, Comparable<BookKeeper.DigestType>

Enclosing class:

BookKeeper

public static enum BookKeeper.DigestType
extends Enum<BookKeeper.DigestType>

There are 2 digest types that can be used for verification. The CRC32 is cheap to compute but does not protect against byzantine bookies (i.e., a bookie might report fake bytes and a matching CRC32). The MAC code is more expensive to compute, but is protected by a password, i.e., a bookie can't report fake bytes with a mathching MAC unless it knows the password

Method Detail

values

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

Returns:

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

valueOf

public static BookKeeper.DigestType 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
