Class org.geotools.data.DefaultTransaction

Examples of org.geotools.data.DefaultTransaction.rollback()

org.geotools.data.DefaultTransaction.rollback()
Rollsback all modifications against this Transaction.
This implementation will call rollback() on all State managed by this Transaction. This allows DataStores to provide their own implementation of rollback().
@throws IOException Encountered problem maintaining transaction State @throws DataSourceException IOException @see org.geotools.data.Transaction#rollback()
