在接下来的代码中可以直接引用这三个已经声明好了的变量。 7 _. S8 J) P% y4 W对于初学者来说，这段神奇的文字就像各种分布一样让人不解其意。" m& E+ ]4 u# {# L( u3 P

This command returns the node with object data attached to it that is the start of the sub-tree that thenode is in. In other words, it returns the object node that contains thenode.

In these fields, c references the node that contains the code, and ownerobject(c) references the object that "owns" that node./ z6 E* j: B$ I9 ?5 B0 g) H% X, G
