Intro

Signals work on a broadcast / receivers model where a signal plus an identifier is broadcast globally across all processes in SGU and any receiver with the same identifier will trigger.

Start signal

This event will start a new process token instance if a signal with matching identifier is received

Intermediate signal catch event

This event will halt execution of a token process instance at its position until a signal with matching identifier is received

Intermediate signal throw event

This event will broadcast a signal with matching identifier whenever a token process instance passes through it (does not halt execution).

End signal

Marks an exit to the process and broadcasts the signal with matching identifier.
