Examples of org.amplafi.flow.impl.FlowActivityImpl

org.amplafi.flow.impl.FlowActivityImpl
defines one activity in the flow. This can be a definition of an activity or the actual activity depending on the state of the Flow parent object. FlowActivityImpl objects may be part of multiple definitions or multiple instances (but not both instances and definitions). FlowActivities must be stateless. FlowActivityImpl instances can be reused between different users and different {@link org.amplafi.flow.Flow}s.
Lifecycle methods:
1. {@link #initializeFlow()} - used to initialize the FlowState with anydefaults for missing values. No modifications should occur in this method.
2. {@link #activate(FlowStepDirection)} - called each time the FlowActivityImpl is made thecurrent FlowActivityImpl. Returns true if the Flow should immediately advance to the next FlowActivityImpl. If this is the last FlowActivityImpl, then the Flow completes. No modifications should occur in this method.
3. {@link #passivate(boolean,FlowStepDirection)} - called each time the FlowActivityImpl was thecurrent FlowActivityImpl and is now no longer the current FlowActivityImpl. Used to validate input as needed. No modifications should occur in this method.
4. {@link #saveChanges()} - called when the flow is completing. Onlyplace where db modifications can be made. This allows canceling the flow to meaningfully revert all changes.
5. {@link #finishFlow(org.amplafi.flow.FlowState)} - called when the flow is finishing.
This structure is in place so that FlowActivities that create relationships are not put into the position of having to be aware of the surrounding Flow and previously created objects. Nor are they aware of the state of the flow.
By convention, FlowActivies are expected to be in a 'flows' package and the FlowActivityImpl subclass' name ends with 'FlowActivityImpl'.
If a FlowActivityImpl is a visible step then the FlowActivityImpl needs a component. The default component type is the grandparent package + the FlowActivityImpl class name with 'FlowActivityImpl' stripped off. For example, fuzzy.flows.FooBarFlowActivity would have a default component of 'fuzzy/FooBar'.
TODO handle return to previous flow issues.
