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 ...;
}
