org.springframework.webflow.engine.impl.FlowExecutionImpl

Default implementation of FlowExecution that uses a stack-based data structure to manage spawned flow sessions. This class is closely coupled with package-private FlowSessionImpl and RequestControlContextImpl . The three classes work together to form a complete flow execution implementation based on a finite state machine.

This implementation of FlowExecution is serializable so it can be safely stored in an HTTP session or other persistent store such as a file, database, or client-side form field. Once deserialized, the {@link FlowExecutionImplFactory} is expected to be used to restore the execution to a usable state. @see FlowExecutionImplFactory @author Keith Donald @author Erwin Vervaet @author Jeremy Grelle

    executionFactory.setExecutionKeyFactory(executionKeyFactory);
    factory = new SerializedFlowExecutionSnapshotFactory(executionFactory, locator);
  }


  public void testCreateSnapshot() {
    FlowExecutionImpl flowExecution = (FlowExecutionImpl) executionFactory.createFlowExecution(flow);
    flowExecution.start(null, new MockExternalContext());
    flowExecution.getActiveSession().getScope().put("foo", "bar");
    FlowExecutionSnapshot snapshot = factory.createSnapshot(flowExecution);
    FlowExecutionImpl flowExecution2 = (FlowExecutionImpl) factory.restoreExecution(snapshot, "myFlow", null,
        flowExecution.getConversationScope(), executionKeyFactory);
    assertNotSame(flowExecution, flowExecution2);
    assertEquals(flowExecution.getDefinition().getId(), flowExecution2.getDefinition().getId());
    assertEquals(flowExecution.getActiveSession().getScope().get("foo"), flowExecution2.getActiveSession()
        .getScope().get("foo"));
    assertEquals(flowExecution.getActiveSession().getState().getId(), flowExecution2.getActiveSession().getState()
        .getId());
    assertNull(flowExecution2.getKey());
    assertSame(flowExecution.getConversationScope(), flowExecution2.getConversationScope());
