Enclosing class:

AbstractReconfiguratorDB<NodeIDType>

public static enum AbstractReconfiguratorDB.RecordNames
extends java.lang.Enum<AbstractReconfiguratorDB.RecordNames>

Constant RC record name keys. Currently there is only one, for the set of all reconfigurators.

Enum Constant Summary

Enum Constants

Enum Constant and Description
AR_AR_NODES The record key for a special name replicated at all current active replicas that simply contains a map of all current active replicas.
AR_NODES The record key for the RC record holding the set of all active replicas.
AR_RC_NODES Similar in spirit to AR_AR_NODES but for reconfigurators.
RC_NODES The record key for the RC record holding the set of all reconfigurators.

Enum Constant Detail

RC_NODES

public static final AbstractReconfiguratorDB.RecordNames RC_NODES

The record key for the RC record holding the set of all reconfigurators. This name is replicated at all reconfigurators and is reconfigured when reconfigurators are added or removed.

AR_NODES

public static final AbstractReconfiguratorDB.RecordNames AR_NODES

The record key for the RC record holding the set of all active replicas. This name is replicated at all reconfigurators and is updated (but not reconfigured) when active replicas are added or removed, and is reconfigured when reconfigurators are added or removed.

AR_AR_NODES

public static final AbstractReconfiguratorDB.RecordNames AR_AR_NODES

The record key for a special name replicated at all current active replicas that simply contains a map of all current active replicas. This name is reconfigured when active replicas are added or removed. It is analogous to AR_NODES replicated at all reconfigurators in that its reconfiguration record is replicated at all reconfigurators, but differs in that the name itself is replicated at active replicas.

AR_RC_NODES

public static final AbstractReconfiguratorDB.RecordNames AR_RC_NODES

Similar in spirit to AR_AR_NODES but for reconfigurators.

Method Detail

values

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

Returns:

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

valueOf

public static AbstractReconfiguratorDB.RecordNames 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
