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, aTxnMandatoryException
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, aTxnNotAllowedException
is thrown.

values
public static PropagationLevel[] 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 (PropagationLevel c : PropagationLevel.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static PropagationLevel 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
