when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>({
  1. required TResult stdout(
    1. Uint8List bytes
    ),
  2. required TResult stderr(
    1. Uint8List bytes
    ),
  3. required TResult exit(
    1. int exitCode
    ),
})

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?>({required TResult Function( Uint8List bytes)  stdout,required TResult Function( Uint8List bytes)  stderr,required TResult Function( int exitCode)  exit,}) {final _that = this;
switch (_that) {
case PrivCommandStdout():
return stdout(_that.bytes);case PrivCommandStderr():
return stderr(_that.bytes);case PrivCommandExit():
return exit(_that.exitCode);}
}
