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( String type, String? description, @JsonKey(name: 'default') int? defaultValue, int? minimum, int? maximum, @JsonKey(name: 'enum') List<int>? enumValues, @JsonKey(name: 'const') int? constValue) $default,) {final _that = this;
switch (_that) {
case _LexInteger():
return $default(_that.type,_that.description,_that.defaultValue,_that.minimum,_that.maximum,_that.enumValues,_that.constValue);case _:
throw StateError('Unexpected subclass');
}
}
