public static interface AsyncTransactionManager.CommitTimestampFuture extends ApiFuture<Timestamp>ApiFuture that returns the commit Timestamp of a Cloud Spanner transaction that is executed using an AsyncTransactionManager. This future is returned by the call to AsyncTransactionStep#commitAsync() of the last step in the transaction.
Implements
com.google.api.core.ApiFuture<com.google.cloud.Timestamp>Methods
get()
public abstract Timestamp get()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.
