Enum Constant Summary

Enum Constants

Enum Constant	Description
ARRIVED	This TransferEvent is dispatched when a set of entries have been transferred to the local member or restored from backup.
ASSIGNED	This TransferEvent is dispatched when a partition has been assigned to the local member.
DEPARTED	This TransferEvent is dispatched when a partition has been successfully transferred from the local member.
DEPARTING	This TransferEvent is dispatched when a set of entries are being transferred from the local member.
LOST	This TransferEvent is dispatched when a partition has been orphaned (data loss may have occurred), and the ownership is assumed by the local member.
RECOVERED	This TransferEvent is dispatched when a set of entries have been recovered from a persistent storage by the local member.
ROLLBACK	This TransferEvent is dispatched when partition transfer has failed and was therefore rolled back.

Enum Constant Detail

ARRIVED

public static final TransferEvent.Type ARRIVED

This TransferEvent is dispatched when a set of entries have been transferred to the local member or restored from backup.

The reason for the event (primary transfer from another member or restore from backup) can be derived as follows:

     TransferEvent event;
     boolean       fRestored = event.getRemoteMember() == event.getLocalMember();
 

ASSIGNED

public static final TransferEvent.Type ASSIGNED

This TransferEvent is dispatched when a partition has been assigned to the local member. This event may only be emitted at the ownership senior during the initial partition assignment.

DEPARTING

public static final TransferEvent.Type DEPARTING

This TransferEvent is dispatched when a set of entries are being transferred from the local member. This event is followed by either a DEPARTED or ROLLBACK event to indicate the success or failure of the transfer.

DEPARTED

public static final TransferEvent.Type DEPARTED

This TransferEvent is dispatched when a partition has been successfully transferred from the local member. To derive the entries associated with the transfer, consumers should subscribe to the DEPARTING event that would precede this event.

LOST

public static final TransferEvent.Type LOST

This TransferEvent is dispatched when a partition has been orphaned (data loss may have occurred), and the ownership is assumed by the local member. This event may only be emitted at the ownership senior.

RECOVERED

public static final TransferEvent.Type RECOVERED

This TransferEvent is dispatched when a set of entries have been recovered from a persistent storage by the local member.

ROLLBACK

public static final TransferEvent.Type ROLLBACK

This TransferEvent is dispatched when partition transfer has failed and was therefore rolled back. To derive the entries associated with the failed transfer, consumers should subscribe to the DEPARTING event that would precede this event.

Method Detail

values

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

Returns:

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

valueOf

public static TransferEvent.Type 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
