Enum Constant Detail

SPYMEMCACHED

public static final KetamaNodeKeyFormatter.Format SPYMEMCACHED

SPYMEMCACHED uses the format traditionally used by spymemcached to map nodes to names. The format is HOSTNAME/IP:PORT-ITERATION

This default implementation uses the socket-address of the MemcachedNode and concatenates it with a hyphen directly against the repetition number for example a key for a particular server's first repetition may look like:

myhost/10.0.2.1-0

for the second repetition

myhost/10.0.2.1-1

for a server where reverse lookups are failing the returned keys may look like

/10.0.2.1-0 and /10.0.2.1-1

LIBMEMCACHED

public static final KetamaNodeKeyFormatter.Format LIBMEMCACHED

LIBMEMCACHED uses the format traditionally used by libmemcached to map nodes to names. The format is HOSTNAME:[PORT]-ITERATION the PORT is not part of the node identifier if it is the default memecached port (11211)

Method Detail

values

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

Returns:

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

valueOf

public static KetamaNodeKeyFormatter.Format valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
