Enum DirMode

java.lang.Object

java.lang.Enum<DirMode>

net.dempsy.cluster.DirMode

All Implemented Interfaces:

Serializable, Comparable<DirMode>

public enum DirMode
extends Enum<DirMode>

This enum represents a bit field.

 The least-significant-bit (LSB) is:
     0: PERSISTENT
     1: EPHEMERAL
 

 The second LSB is:
     0: NON-SEQUENTIAL
     1: SEQUENTIAL
 

For SEQUENTIAL nodes, all implementations are required to make the resulting versioned subdirectories both lexographically sortable from the highest to lowest revision and also the SEQUENTIAL suffix will be convertable to an integer.

Method Detail

values

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

Returns:

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

valueOf

public static DirMode 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
