Method Details

get

Timestamp get()
       throws AbortedException,
InterruptedException,
ExecutionException

Returns the commit timestamp of the transaction. Getting this value should always be done in order to ensure that the transaction succeeded. If any of the steps in the transaction fails with an uncaught exception, this method will automatically stop the transaction at that point and the exception will be returned as the cause of the ExecutionException that is thrown by this method.

Specified by:

get in interface Future<Timestamp>

Throws:

AbortedException - if the transaction was aborted by Cloud Spanner and needs to be retried.

InterruptedException

ExecutionException
