Enum Class TransactionPhase

Serializable, Comparable<TransactionPhase>, Constable

public enum TransactionPhase extends 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 Synchronization callback cannot be registered due to the transaction being already marked for rollback or in state where Synchronization callbacks cannot be registered, the BEFORE_COMPLETION, AFTER_COMPLETION and AFTER_FAILURE observer methods are notified at the same time as other observers, but AFTER_SUCCESS observer methods get skipped.

    Description
    Identifies an after completion observer method, called during the after completion phase of the transaction.
    Identifies an after failure observer method, called during the after completion phase of the transaction, only when the transaction fails.
    Identifies an after success observer method, called during the after completion phase of the transaction, only when the transaction completes successfully.
    Identifies a before completion observer method, called during the before completion phase of the transaction.
    Identifies a regular observer method, called when the event is fired.

    • 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 Synchronization callback cannot be registered due to the transaction being already marked for rollback or in state where 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 Synchronization callback cannot be registered due to the transaction being already marked for rollback or in state where 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 Synchronization callback cannot be registered due to the transaction being already marked for rollback or in state where 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 class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static TransactionPhase valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null
