Enum<HaStateType>

com.tailf.ha.HaStateType

All Implemented Interfaces:

Serializable, Comparable<HaStateType>

public enum HaStateType
extends Enum<HaStateType>

This enum describes the different states a HA node can be in.

Enum Constant Summary

Enum Constants

Enum Constant and Description
MASTER MASTER implies that the node is master in a HA cluster.
NONE NONE implies that the node is not participating in a HA cluster.
SLAVE SLAVE implies that the node is slave in a HA cluster.
SLAVE_RELAY SLAVE_RELAY implies that the node is slave in a HA cluster, that may also have "sub-slaves" (after a beRelay() call).

Enum Constant Detail

NONE

public static final HaStateType NONE

NONE implies that the node is not participating in a HA cluster.

SLAVE

public static final HaStateType SLAVE

SLAVE implies that the node is slave in a HA cluster.

MASTER

public static final HaStateType MASTER

MASTER implies that the node is master in a HA cluster.

SLAVE_RELAY implies that the node is slave in a HA cluster, that may also have "sub-slaves" (after a beRelay() call).

Method Detail

values

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

Returns:

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

valueOf

public static HaStateType 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

getValue

public int getValue()

Get the integer value represented by this enum value.

Returns:

integer value for enum

valueOf

public static HaStateType valueOf(int i)

Instantiates an HaStateType from an integer value.

Parameters:

i - - integer value representing the HaStateType

Returns:

an HaStateType object
