parseOn method

  1. @override
  2. @noBoundsChecks
Result<R> parseOn(
  1. Context context
)
override

Parses the given context.

Overridden in concrete subclasses to implement the parser-specific logic. Takes a parse context and returns the resulting context, which is either a Success or Failure context.

Implementation

@override
@noBoundsChecks
Result<R> parseOn(Context context) {
  // Check the first choice:
  final result = children[0].parseOn(context);
  if (result is! Failure) return result;
  var failure = result;
  // Check all other choices:
  for (var i = 1; i < children.length; i++) {
    final result = children[i].parseOn(context);
    if (result is! Failure) return result;
    failure = failureJoiner(failure, result);
  }
  return failure;
}
