when<TResult extends Object?> method
- @optionalTypeArgs
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(@JsonKey(name: 'certificateFile') String? certFile, @JsonKey(name: 'certificate') List<String>? certStr, String? keyFile, @JsonKey(name: 'key') List<String>? keyStr, TLSCertificateUsage? usage, int? ocspStapling, bool? oneTimeLoading, bool? buildChain) $default,) {final _that = this;
switch (_that) {
case _TLSCertConfig():
return $default(_that.certFile,_that.certStr,_that.keyFile,_that.keyStr,_that.usage,_that.ocspStapling,_that.oneTimeLoading,_that.buildChain);case _:
throw StateError('Unexpected subclass');
}
