Method Detail

timeout

public TransactionRunnerImpl timeout(int seconds)

Description copied from interface: TransactionRunnerOptions

Sets the transaction timeout for transactions created by this runner. A value of zero refers to the system default.

Specified by:

timeout in interface TransactionRunnerOptions

Parameters:

seconds - The timeout in seconds

Returns:

This builder

exceptionHandler

public TransactionRunnerImpl exceptionHandler(Function<Throwable,TransactionExceptionResult> handler)

Description copied from interface: TransactionRunnerOptions

Provides an exception handler that can make a decision to rollback or commit based on the type of exception. If the predicate returns TransactionExceptionResult.ROLLBACK the transaction is rolled back, otherwise it is committed.

This exception will still be propagated to the caller, so this method should not log or perform any other actions other than determine what should happen to the current transaction.

By default, the exception is always rolled back.

Specified by:

exceptionHandler in interface TransactionRunnerOptions

Parameters:

handler - The exception handler

Returns:

This builder

run

public void run(Runnable task)

Description copied from interface: TransactionRunner

Runs the given runnable, starting/suspending transactions as required by the selected semantics.

Specified by:

run in interface TransactionRunner

Parameters:

task - A task to run with the selected transaction semantics.

call

public <T> T call(Callable<T> task)

Description copied from interface: TransactionRunner

Calls the given callable, starting/suspending transactions as required by the selected semantics.

If the task throws a checked exception it will be wrapped with a QuarkusTransactionException

Specified by:

call in interface TransactionRunner

Parameters:

task - A task to run with the selected transaction semantics.

Returns:

The value returned by task.call().
