All Implemented Interfaces:

Serializable, Comparable<CdbSubscriptionFlagType>

public enum CdbSubscriptionFlagType
extends Enum<CdbSubscriptionFlagType>

Distinguish the different types of subscription notifications

Enum Constant Summary

Enum Constants

Enum Constant and Description
CDB_SUB_FLAG_HA_IS_SLAVE This bit is set when the system is in HA slave mode.
CDB_SUB_FLAG_HA_SYNC This bit is set when the cause of the subscription notification is initial synchronization of a HA slave from CDB on the master.
CDB_SUB_FLAG_IS_LAST This bit is set when this notification is the last of its type for this subscription socket.
CDB_SUB_FLAG_REVERT If a confirming commit is aborted it will look to the CDB subscribe as if a transaction happened that is the reverse of what the original transaction was.
CDB_SUB_FLAG_TRIGGER This bit is set when the cause of the subscription notification is that someone called Cdb.triggerSubscriptions(int[]).

Enum Constant Detail

CDB_SUB_FLAG_IS_LAST

public static final CdbSubscriptionFlagType CDB_SUB_FLAG_IS_LAST

This bit is set when this notification is the last of its type for this subscription socket.

CDB_SUB_FLAG_TRIGGER

public static final CdbSubscriptionFlagType CDB_SUB_FLAG_TRIGGER

This bit is set when the cause of the subscription notification is that someone called Cdb.triggerSubscriptions(int[]).

CDB_SUB_FLAG_REVERT

public static final CdbSubscriptionFlagType CDB_SUB_FLAG_REVERT

If a confirming commit is aborted it will look to the CDB subscribe as if a transaction happened that is the reverse of what the original transaction was. This bit will be set when such a transaction is the cause of the notification. Note that for a two-phase subscriber both a prepare and a commit notification is delivered. However it is not possible to reply by calling CdbSubscription.abortTransaction(CdbExtendedException) for the prepare notification in this case, instead the subscriber will have to take appropriate backup action if it needs to abort (for example: raise an alarm, restart, or even reboot the system).

CDB_SUB_FLAG_HA_SYNC

public static final CdbSubscriptionFlagType CDB_SUB_FLAG_HA_SYNC

This bit is set when the cause of the subscription notification is initial synchronization of a HA slave from CDB on the master.

CDB_SUB_FLAG_HA_IS_SLAVE

public static final CdbSubscriptionFlagType CDB_SUB_FLAG_HA_IS_SLAVE

This bit is set when the system is in HA slave mode.

Method Detail

values

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

Returns:

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

valueOf

public static CdbSubscriptionFlagType 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()

valueOf

public static CdbSubscriptionFlagType valueOf(int i)

enumSetOf

public static EnumSet<CdbSubscriptionFlagType> enumSetOf(int i)
