-
#at(event) ⇒ Object
Creates a new behavior sensitive to +event+ including the connection converted to a transmission, and replace the former by the new behavior.
-
#hif(condition) ⇒ Object
Creates a new behavior with an if statement from +condition+ enclosing the connection converted to a transmission, and replace the former by the new behavior.
-
#to_expr ⇒ Object
Converts the connection to a comparison expression.
-
#to_low ⇒ Object
Converts the connection to HDLRuby::Low.

#hif(condition) ⇒ Object
Creates a new behavior with an if statement from +condition+ enclosing the connection converted to a transmission, and replace the former by the new behavior.
NOTE: the else part is defined through the helse method.

High.top_user.add_behavior(behavior) # Remove the connection High.top_user.delete_connection!(self) end |
#to_expr ⇒ Object
Converts the connection to a comparison expression.
NOTE: required because the <= operator is ambigous and by default produces a Transmit or a Connection.

Converts the connection to HDLRuby::Low.
