processState method

This method is always called by the processing engine when the state is activated by the follow-up transition.

Syntax

 void processState(
    SmappStateProcessingContext context,
    SmappStateProcessingAction action
) throws MwizProcessingException,
    DBException

The reference implementation provided in this method is described as follow. This reference implementation is provided for to help simplifying a typical state development. This implementation is sufficient for most cases.

Retrieve the input and output attributes value from the datasource, and bind the value to the input and output attributes. Note: these attributes are persisted to the datasource as a session variable.
Delegate the call to the subclass method for processing the state logic, processStateLogic(SmappStateProcessingContext, SmappStateProcessingAction).
The delegate method, processStateLogic(SmappStateProcessingContext, SmappStateProcessingAction) returns the follow-up transition as SmappState object.
If the follow-up transition (SmappState) returned by the processStateLogic() is not null, communicate the follow-up transition to the processing engine using the SmappStateProcessingAction object, as follow. action.continueProcessing(followUpTransition); Otherwise, if the returned follow-up transition is null, then the processing engine will terminate the application. NOTE: if a SmappStateProcessingAction object is not set the engine will terminate the flow.
Used by: processing engine

Parameters
- context the state processing context containing all the necessary object needed while processing the state.
- action mechanism to communicate suggested follow-up action to the processing engine
Exceptions
- MwizProcessingException any exceptions that warrant terminating the application
- DBException any database exceptions that warrant terminating the application
- CryptoException any encryption exceptions that warrant terminating the application
