map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>({ required TResult str(PyArgument_Str value), required TResult int(PyArgument_Int value), required TResult float(PyArgument_Float value), required TResult bool(PyArgument_Bool value), required TResult listStr(PyArgument_ListStr value), required TResult listInt(PyArgument_ListInt value), })

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case final Subclass2 value:
    return ...;
}

Implementation

@optionalTypeArgs

  required TResult Function(PyArgument_Str value) str,
  required TResult Function(PyArgument_Int value) int,
  required TResult Function(PyArgument_Float value) float,
  required TResult Function(PyArgument_Bool value) bool,
  required TResult Function(PyArgument_ListStr value) listStr,
  required TResult Function(PyArgument_ListInt value) listInt,
}) {
  final _that = this;
  switch (_that) {
    case PyArgument_Str():
      return str(_that);
    case PyArgument_Int():

    case PyArgument_Float():
      return float(_that);
    case PyArgument_Bool():
