map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult slp(
    1. SlpTokenType value
    ),
  2. required TResult alp(
    1. AlpTokenType value
    ),
  3. required TResult unknown(
    1. UnknownTokenType 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 TResult map<TResult extends Object?>({required TResult Function( SlpTokenType value)  slp,required TResult Function( AlpTokenType value)  alp,required TResult Function( UnknownTokenType value)  unknown,}){
final _that = this;
switch (_that) {
case SlpTokenType():
return slp(_that);case AlpTokenType():
return alp(_that);case UnknownTokenType():
return unknown(_that);}
}
