All Implemented Interfaces:

Closeable, AutoCloseable, org.geotools.api.data.Transaction

public class AtomicWriteTransaction
extends Object

Transaction object that enforces atomic writes - this ensures that a feature is not modified between when it's read and when it's updated. Does not support normal transaction operations, such as commit or rollback, and instead operates like auto-commit.
