when<TResult extends Object?> method
- @optionalTypeArgs
- TResult $default(
- String? action,
- XrayNetworkList? network,
- XrayPortList? port,
- XrayStringList? ip,
- XrayInt32Range? blockDelay,
A switch-like method, using callbacks.
As opposed to map, this offers destructuring.
It is equivalent to doing:
switch (sealedClass) {
case Subclass(:final field):
return ...;
case Subclass2(:final field2):
return ...;
}
