Enum Class TransactionPropagation

java.lang.Object

java.lang.Enum<TransactionPropagation>

st.orm.TransactionPropagation

All Implemented Interfaces:

Serializable, Comparable<TransactionPropagation>, Constable

public enum TransactionPropagation
extends Enum<TransactionPropagation>

Defines how a transaction block relates to a transaction that is already active when the block starts.

The semantics mirror the standard transaction propagation behaviors. The default is REQUIRED.

Since:

1.13

Enum Constant Summary

Enum Constants

Enum Constant	Description
MANDATORY	Joins the active transaction; fails when none is active.
NESTED	Runs within a nested transaction (a savepoint) when a transaction is active; otherwise starts a new one.
NEVER	Runs without a transaction; fails when one is active.
NOT_SUPPORTED	Runs without a transaction, suspending the active one for the duration of the block.
REQUIRED	Joins the active transaction, or starts a new one when none is active.
REQUIRES_NEW	Always starts a new, independent transaction, suspending the active one for the duration of the block.
SUPPORTS	Joins the active transaction when one is active; otherwise runs without a transaction.

Method Summary

Modifier and Type	Method	Description
static TransactionPropagation	valueOf(String name)	Returns the enum constant of this class with the specified name.
static TransactionPropagation[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

REQUIRED

public static final TransactionPropagation REQUIRED

Joins the active transaction, or starts a new one when none is active. The default.

SUPPORTS

public static final TransactionPropagation SUPPORTS

Joins the active transaction when one is active; otherwise runs without a transaction.

MANDATORY

public static final TransactionPropagation MANDATORY

Joins the active transaction; fails when none is active.

REQUIRES_NEW

public static final TransactionPropagation REQUIRES_NEW

Always starts a new, independent transaction, suspending the active one for the duration of the block.

NOT_SUPPORTED

public static final TransactionPropagation NOT_SUPPORTED

Runs without a transaction, suspending the active one for the duration of the block.

NEVER

public static final TransactionPropagation NEVER

Runs without a transaction; fails when one is active.

NESTED

public static final TransactionPropagation NESTED

Runs within a nested transaction (a savepoint) when a transaction is active; otherwise starts a new one.

Method Details

values

public static TransactionPropagation[] 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 TransactionPropagation 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
