public interface CDOFileTransaction extends CDOTransaction
A transaction whose uncommitted changes can be persisted in a local file and explicitly pushed to the repository. A normal CDOUserTransaction.commit() exports changes to the file and does not commit to the repository. Repository persistence is performed only by push().

The inherited CDOUserTransaction.rollback() operation is not supported, and inherited commit overloads that accept a callable or runnable are rejected because they cannot provide unambiguous local-export semantics.
