new (source, node_id, location, flags, receiver, opening_loc, arguments, closing_loc, block)

源代码

# File lib/prism/node.rb, line 9622
def initialize(source, node_id, location, flags, receiver, opening_loc, arguments, closing_loc, block)
  @source = source
  @node_id = node_id

初始化一个新的 IndexTargetNode 节点。

type ()

=== (other)

源代码

# File lib/prism/node.rb, line 9753
def ===(other)
  other.is_a?(IndexTargetNode) &&
    (flags === other.flags) &&
    (receiver === other.receiver) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (arguments === other.arguments) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (block === other.block)
end

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