Interface ThreadedTransactionalGraph

All Superinterfaces:

Graph, TransactionalGraph

public interface ThreadedTransactionalGraph
extends TransactionalGraph

ThreadedTransactionalGraph provides more fine grained control over the transactional context. While TransactionalGraph binds each transaction to the executing thread, ThreadedTransactionalGraph's newTransaction() returns a TransactionalGraph that represents its own transactional context independent of the executing thread. Hence, one can have multiple threads operating against a single transaction represented by the returned TransactionalGraph object. This is useful for parallelizing graph algorithms. Note, that one needs to call TransactionalGraph.commit() or TransactionalGraph.rollback() to close the transactions returned by newTransaction().

TransactionalGraph newTransaction()

Returns a TransactionalGraph that represents a transactional context independent of the executing transaction.

Returns:

A transactional context. Invoking TransactionalGraph.shutdown() successfully commits the transaction.
