Method Detail

commit

void commit(Graph graph)

Notify this worker that a transaction on a specified graph is being committed, and give the worker an opportunity to rollback the transaction. If the worker wishes to vote to rollback, it should call the Transaction.rollback() method on the supplied graph.

A worker may inject transaction side-effects by adding new statements to the graph. If any worker adds side-effects, then another round of commit notifications will commence. The worker may inspect the statements added since the last round by calling graph.tx().asList().

Parameters:

graph - The graph whose transaction has ended.
