Examples of StoreTransaction

co.paralleluniverse.galaxy.StoreTransaction
Represents a grid data-store transaction. @see Store#beginTransaction()
com.hp.hpl.jena.gvs.StoreTransaction
Represents a set of actions on a store by one source at one point in time. @author reto

A transaction handle uniquely identifies a transaction on the storage backend.
All modifications to the storage backend must occur within the context of a single transaction. Such a transaction is identified to the Titan middleware by a StoreTransaction. Graph transactions rely on the existence of a storage backend transaction.
Note, that a StoreTransaction by itself does not provide any isolation or consistency guarantees (e.g. ACID). Graph Transactions can only extend such guarantees if they are supported by the respective storage backend. @author Matthias Bröcheler (me@matthiasb.com);
