User custom signal with the same api as the built-in signals.
Naming the function signature arguments, if any, is recommended for improved error messages:
final myCustomSignal = new CustomSignal<(name:String) -> Void>("myCustomSignal");Constructor
new(name:String = "")
Create a new custom signal.
Parameters:
name | Optional name, used for improved debug info. |
|---|
Methods
connect(callback:T):Void
Connects the custom signal to the callback.
A signal can only be connected once to a callback. It will throw an error if already connected.
To avoid this, first, use isConnected to check for existing connections.
disconnect(callback:T):Void
Disconnects the custom signal from the callback.
If you try to disconnect a connection that does not exist, the method will throw an error.
Use isConnected to ensure that the connection exists.
emitSignal(args:Rest<Any>):Void
Emit the custom signal.
The arguments type and number are checked at compile time.
isConnected(callback:T):Bool
Returns true if a connection exists between this custom signal and the callback.
