Enum Constant Detail

• RequiresNew

  public static final PropagationLevel RequiresNew

  Indicates that a new transaction always is started, even when there is an active transaction. The active transaction is postponed and used again after the nested transaction commits. It could be that the outer transaction conflicts made on changes by the inner transaction.

• Requires

  public static final PropagationLevel Requires

  Indicates that a new transaction will be used if none exists. If one exists, the logic will lift on that transaction. This is the default propagation level.

• Mandatory

  public static final PropagationLevel Mandatory

  Indicates that a transaction should always be available. If not, a TxnMandatoryException is thrown.

• Supports

  public static final PropagationLevel Supports

  Indicates that it the logic can either be run with or without transaction.

• Never

  public static final PropagationLevel Never

  Indicates that no active transaction should be available. If a transaction is found, a TxnNotAllowedException is thrown.
