visit method

void visit(void callback(String? pkg, String lib, String? cls, String? fun, ProgramInfoNode n,))

Recursively visit all function nodes, which have FunctionInfo.info populated.

Implementation

void visit(
    void Function(String? pkg, String lib, String? cls, String? fun,
            ProgramInfoNode n)
        callback) {
  final context = List<String?>.filled(NodeType.values.length, null);

  void recurse(ProgramInfoNode node) {
    final prevContext = context[node._type];
    if (prevContext != null && node._type == NodeType.functionNode.index) {
      context[node._type] = '$prevContext.${node.name}';
    } else {
      context[node._type] = node.name;
    }

    final pkg = context[NodeType.packageNode.index];
    final lib = context[NodeType.libraryNode.index];
    final cls = context[NodeType.classNode.index];
    final mem = context[NodeType.functionNode.index];
    callback(pkg, lib!, cls, mem, node);

    for (var child in node.children.values) {
      recurse(child);
    }

    context[node._type] = prevContext;
  }

  recurse(root);
}
