Enum Constant Detail

DEFAULT

public static final Replication DEFAULT

Default replication is used. getFactor(int) makes no sense for this constant, a default should be defined by the implementation and such default should be used,

NONE

public static final Replication NONE

Data is no replicated

ONE

public static final Replication ONE

One copy of the data is kept

QUORUM

public static final Replication QUORUM

The data plus its copies form a quorum

FULL

public static final Replication FULL

Data is fully replicated: Data plus its copies are located in all the cluster

Method Detail

values

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

Returns:

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

valueOf

public static Replication 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

getFactor

public abstract int getFactor(int clusterSize)

Gets a numeric replication factor for the given clusterSize

Parameters:

clusterSize - size of the cluster

Returns:

a replication factor
