when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. XrayInt32Range? maxConcurrency,
    2. XrayInt32Range? maxConnections,
    3. XrayInt32Range? cMaxReuseTimes,
    4. XrayInt32Range? hMaxRequestTimes,
    5. XrayInt32Range? hMaxReusableSecs,
    6. int? hKeepAlivePeriod,
    )
)

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( XrayInt32Range? maxConcurrency,  XrayInt32Range? maxConnections,  XrayInt32Range? cMaxReuseTimes,  XrayInt32Range? hMaxRequestTimes,  XrayInt32Range? hMaxReusableSecs,  int? hKeepAlivePeriod)  $default,) {final _that = this;
switch (_that) {
case _XmuxConfig():
return $default(_that.maxConcurrency,_that.maxConnections,_that.cMaxReuseTimes,_that.hMaxRequestTimes,_that.hMaxReusableSecs,_that.hKeepAlivePeriod);case _:
  throw StateError('Unexpected subclass');

}
