State Transition Tables give you a different perspective of your model. State Transition Tables enables you to easily monitor and report on the most complicated State Machine Diagrams, revealing subtle errors before they have widespread effects.
If there is no window below the diagram editor, go to [View] – [Show/Hide Extra View] to open.
When you open a Statemachine diagram, the state transition table conveniently appears below the diagram.
You can switch the table view from two different point views, “States to states” and “States to Events” by combo box.
You can filter out States that you do not want to include in the State Transition table.
Click the [Config] button, and tick the checkboxes of the States that you want to show in the State Transition Table. You can also change the order of the states in the table.
When you have a “State – Event” view, you can fill the blank cell with “ignore” or “cannot happen”. This cannot be done or is invisible on the Statemachine diagram only. So checking all the blank cells and defining them as “ignore” or “cannot happen” will helps to make your diagrams more accurate.
You can export the table to Excel by clicking the Export button.
Having a table exported and check along with diagram would be very effective especially when the statemachine diagram is complete and has much information.
Currently, the following models are not supported for State Transition Table.
