Event Icons are always Circular
Throwing Events -> Triggering something
Catching Events -> Reacting to a Trigger : Catching Message Event
Types of Event
Events that occur in the middle of the process (between activities) are called Intermediate events (thin double line).
Events that occur at the end of the process are called End events(thick single line) and every process has at least one end event.
Boundary Events -> Are Attached to Tasks(Rounded Rectangle) and is always an Intermediate Event
They can be Interrupting and Non-Interrupting
Interrupting - They disturb flow and block main process - Solid Line (Default)
Non-Interrupting - They don't disturb the actual flow and continue in parallel - Dashed Line
An intermediate signal throw event is visualized as a typical intermediate event (circle with smaller circle inside), with the signal icon inside.
The signal icon is black (filled), to indicate its throw semantics.
Cancel Boundary Event
Compensation Boundary Event
The compensation boundary event is activated when the activity it is attached to completes successfully.
At this point, the corresponding subscription to the compensation events is created.
The subscription is removed either when a compensation event is triggered or when the corresponding process instance ends.
