root property
SymbolTable<T> ?
root
Resolves the symbol table at the very root of the hierarchy.
This value is memoized to speed up future lookups.
Implementation
SymbolTable<T>? get root {
if (_root != null) return _root;
var out = this;
while (out._parent != null) {
out = out._parent!;
}
return _root = out;
}
