An AcceptEventAction
with the Trigger::port set to be iKeypad:I_Keypad
unmarshalls a S_Digit
signal to extract the digit:Integer
. It then sends this to the append
operation of its number:Number
.
The number:Number
also provides the accumulated digits so far as a String. This String is printed prefixed with the id
of the receiver (so we can see which one was connected). And the String is then sent out via the oDisplay:~I_Display
Port.
