define method

@override void define(String id, dynamic decl, { bool override = false, bool throws = true, })

define a declaration in this namespace, the defined id could be different from declaration's id

Implementation

@override
void define(String id, dynamic decl,
    {bool override = false, bool throws = true}) {
  if (!symbols.containsKey(id)) {
    symbols[id] = decl;
  } else {
    if (!override) {
      if (throws) {
        throw HTError.defined(id, HTErrorType.staticWarning);
      }
    } else {
      // final existedValue = symbols[id];
      // if (existedValue is HTDeclarationNamespace &&
      //     decl is HTDeclarationNamespace) {
      //   // TODO: merge namespace?
      // } else {
      //   symbols[id] = decl;
      // }
      symbols[id] = decl;
    }
  }
