Examples of org.amplafi.flow.FlowState

org.amplafi.flow.FlowState
Implementations hold the state of an active Flow. Implementers should expect to be stored in a Session and should be serializable.

        FlowTestingUtils flowTestingUtils = new FlowTestingUtils();
        flowTestingUtils.getFlowTranslatorResolver().resolveFlow(flow);
        flowTestingUtils.getFlowDefinitionsManager().addDefinition(FLOW_TYPE, flow);
        FlowManagement flowManagement = flowTestingUtils.getFlowManagement();
        String returnToFlowLookupKey = null;
        FlowState flowState = flowManagement.startFlowState(FLOW_TYPE, true, initialFlowState, returnToFlowLookupKey);
        SampleEnum type =flowState.getCurrentActivity().getProperty("foo");
        assertEquals(type, SampleEnum.EXTERNAL, "(looking for property 'foo') FlowState="+flowState);
        type =flowState.getProperty("fa1fp", SampleEnum.class);
