class Prism::SuperNode

表示带有括号或参数的 super 关键字的使用。

super()
^^^^^^^

super foo, bar
^^^^^^^^^^^^^^

如果未提供参数（块除外），则会是 ForwardingSuperNode。

属性

arguments [R]

只有在有空括号时（例如 super()）才可能是 nil。

block [R]

attr_reader block: BlockNode | BlockArgumentNode | nil

=== (other)

Source

# File lib/prism/node.rb, line 17394
def ===(other)
  other.is_a?(SuperNode) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (lparen_loc.nil? == other.lparen_loc.nil?) &&
    (arguments === other.arguments) &&
    (rparen_loc.nil? == other.rparen_loc.nil?) &&
    (block === other.block)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。
