when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? name,
    2. String? alpn,
    3. String? path,
    4. XrayFallbackType? type,
    5. Object? dest,
    6. int? xver,
    )
)

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 ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String? name,  String? alpn,  String? path,  XrayFallbackType? type,  Object? dest,  int? xver)  $default,) {final _that = this;
switch (_that) {
case _TrojanInboundFallback():
return $default(_that.name,_that.alpn,_that.path,_that.type,_that.dest,_that.xver);case _:
  throw StateError('Unexpected subclass');

}
}
