new(source, node_id, location, flags, body, opening_loc, closing_loc) 点击切换源代码

初始化一个新的 ParenthesesNode 节点。

# File prism/node.rb, line 14264
def initialize(source, node_id, location, flags, body, opening_loc, closing_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @body = body
  @opening_loc = opening_loc
  @closing_loc = closing_loc
end

公共实例方法

===(other) 点击切换源代码

为节点实现 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。

# File prism/node.rb, line 14365
def ===(other)
  other.is_a?(ParenthesesNode) &&
    (body === other.body) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?)
