Method Details

performInTransaction

public <T> T performInTransaction(TransactionalOperation<T> op)

Description copied from interface: TransactionManager

Starts a new transaction (or joins an existing one) calling TransactionalOperation.perform(), and then committing or rolling back the transaction.

Specified by:

performInTransaction in interface TransactionManager

Type Parameters:

T - returned value type

Parameters:

op - an operation to perform within the transaction.

Returns:

a value returned by the "op" operation.

performInTransaction

public <T> T performInTransaction(TransactionalOperation<T> op,
 TransactionListener callback)

Description copied from interface: TransactionManager

Starts a new transaction (or joins an existing one) calling TransactionalOperation.perform(), and then committing or rolling back the transaction. As transaction goes through stages, callback methods are invoked allowing the caller to customize transaction parameters.

Specified by:

performInTransaction in interface TransactionManager

Type Parameters:

T - returned value type

Parameters:

op - an operation to perform within the transaction.

callback - a callback to notify as transaction progresses through stages.

Returns:

a value returned by the "op" operation.

performInTransaction

public <T> T performInTransaction(TransactionalOperation<T> op,
 TransactionDescriptor descriptor)

Description copied from interface: TransactionManager

Performs operation in a transaction which parameters described by descriptor.

Specified by:

performInTransaction in interface TransactionManager

Type Parameters:

T - result type

Parameters:

op - an operation to perform within the transaction.

descriptor - transaction descriptor

Returns:

a value returned by the "op" operation.

Since:

4.1

performInTransaction

public <T> T performInTransaction(TransactionalOperation<T> op,
 TransactionListener callback,
 TransactionDescriptor descriptor)

Description copied from interface: TransactionManager

Performs operation in a transaction which parameters described by descriptor. As transaction goes through stages, callback methods are invoked allowing the caller to customize transaction parameters.

Specified by:

performInTransaction in interface TransactionManager

Type Parameters:

T - returned value type

Parameters:

op - an operation to perform within the transaction.

callback - a callback to notify as transaction progresses through stages.

descriptor - transaction descriptor

Returns:

a value returned by the "op" operation.

Since:

4.1

performInTransaction

public <T> T performInTransaction(TransactionalOperation<T> op,
 TransactionFactory transactionFactory)

Description copied from interface: TransactionManager

Performs an operation in a transaction created by the supplied factory, instead of the configured one. This lets callers run an operation in a special transaction, such as a ReadOnlyTransaction. Behaves like TransactionPropagation.NESTED - joining an existing transaction if one is bound, otherwise creating a new one from the given factory.

Specified by:

performInTransaction in interface TransactionManager

Type Parameters:

T - returned value type

Parameters:

op - an operation to perform within the transaction.

transactionFactory - a factory for the transaction to run the operation in.

Returns:

a value returned by the "op" operation.

Since:

5.0
