public enum TransactionPhase extends java.lang.Enum<TransactionPhase>
Distinguishes the various kinds of transactional observer methods from regular observer methods which are notified immediately.
Transactional observer methods are observer methods which receive event notifications during the before or after completion phase of the transaction in which the event was fired. If no transaction is in progress when the event is fired, they are notified at the same time as other observers. If the transaction is in progress, but

callback cannot be registered due to the transaction being already marked for rollback or in state wherejakarta.transaction.Synchronization
callbacks cannot be registered, theBEFORE_COMPLETION
,AFTER_COMPLETION
andAFTER_FAILURE
observer methods are notified at the same time as other observers, butAFTER_SUCCESS
observer methods get skipped.- Author:

IN_PROGRESS
public static final TransactionPhase IN_PROGRESS
Identifies a regular observer method, called when the event is fired.
-
BEFORE_COMPLETION
public static final TransactionPhase BEFORE_COMPLETION
Identifies a before completion observer method, called during the before completion phase of the transaction.
Transactional observer will be notified if there is no transaction in progress, or the transaction is in progress, but
jakarta.transaction.Synchronization
callback cannot be registered due to the transaction being already marked for rollback or in state wherejakarta.transaction.Synchronization
callbacks cannot be registered.
-
AFTER_COMPLETION
public static final TransactionPhase AFTER_COMPLETION
Identifies an after completion observer method, called during the after completion phase of the transaction.
Transactional observer will be notified if there is no transaction in progress, or the transaction is in progress, but
jakarta.transaction.Synchronization
callback cannot be registered due to the transaction being already marked for rollback or in state wherejakarta.transaction.Synchronization
callbacks cannot be registered.
-
AFTER_FAILURE
public static final TransactionPhase AFTER_FAILURE
Identifies an after failure observer method, called during the after completion phase of the transaction, only when the transaction fails.
Transactional observer will be notified will also get invoked if there is no transaction in progress, or the transaction is in progress, but
jakarta.transaction.Synchronization
callback cannot be registered due to the transaction being already marked for rollback or in state wherejakarta.transaction.Synchronization
callbacks cannot be registered.
-
AFTER_SUCCESS
public static final TransactionPhase AFTER_SUCCESS
Identifies an after success observer method, called during the after completion phase of the transaction, only when the transaction completes successfully.

values
public static TransactionPhase[] 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 (TransactionPhase c : TransactionPhase.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static TransactionPhase 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 namejava.lang.NullPointerException
- if the argument is null
