public abstract class DelegatingTransactionDefinition extends Object implements TransactionDefinition, Serializable
TransactionDefinition implementation that delegates all calls to a given target
TransactionDefinition instance. Abstract because it is meant to be subclassed,
with subclasses overriding specific methods that are not supposed to simply delegate
to the target instance.ISOLATION_DEFAULT, ISOLATION_READ_COMMITTED, ISOLATION_READ_UNCOMMITTED, ISOLATION_REPEATABLE_READ, ISOLATION_SERIALIZABLE, PROPAGATION_MANDATORY, PROPAGATION_NESTED, PROPAGATION_NEVER, PROPAGATION_NOT_SUPPORTED, PROPAGATION_REQUIRED, PROPAGATION_REQUIRES_NEW, PROPAGATION_SUPPORTS, TIMEOUT_DEFAULT| Constructor and Description |

TransactionDefinitionMust return one of the PROPAGATION_XXX constants
defined on this interface.

TransactionSynchronizationManager.isActualTransactionActive()public int getIsolationLevel()
TransactionDefinitionMust return one of the ISOLATION_XXX constants
defined on this interface.
Only makes sense in combination with TransactionDefinition.PROPAGATION_REQUIRED
or TransactionDefinition.PROPAGATION_REQUIRES_NEW.
Note that a transaction manager that does not support custom isolation levels
will throw an exception when given any other level than TransactionDefinition.ISOLATION_DEFAULT.
getIsolationLevel in interface TransactionDefinitionpublic int getTimeout()
TransactionDefinitionMust return a number of seconds, or TransactionDefinition.TIMEOUT_DEFAULT.
Only makes sense in combination with TransactionDefinition.PROPAGATION_REQUIRED
or TransactionDefinition.PROPAGATION_REQUIRES_NEW.
Note that a transaction manager that does not support timeouts will throw
an exception when given any other timeout than TransactionDefinition.TIMEOUT_DEFAULT.

TransactionDefinitionThe read-only flag applies to any transaction context, whether
backed by an actual resource transaction
(TransactionDefinition.PROPAGATION_REQUIRED/TransactionDefinition.PROPAGATION_REQUIRES_NEW) or
operating non-transactionally at the resource level
(TransactionDefinition.PROPAGATION_SUPPORTS). In the latter case, the flag will
only apply to managed resources within the application, such as a
Hibernate Session.
This just serves as a hint for the actual transaction subsystem; it will not necessarily cause failure of write access attempts. A transaction manager which cannot interpret the read-only hint will not throw an exception when asked for a read-only transaction.
isReadOnly in interface TransactionDefinitiontrue if the transaction is to be optimized as read-onlyTransactionSynchronization.beforeCommit(boolean),

TransactionDefinitionnull.
This will be used as the transaction name to be shown in a transaction monitor, if applicable (for example, WebLogic's).
In case of Spring's declarative transactions, the exposed name will be
the fully-qualified class name + "." + method name (by default).
