new (source, node_id, location, flags, opening_loc, content_loc, closing_loc, unescaped)

源

# File lib/prism/node.rb, line 12351
def initialize(source, node_id, location, flags, opening_loc, content_loc, closing_loc, unescaped)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @opening_loc = opening_loc
  @content_loc = content_loc
  @closing_loc = closing_loc
  @unescaped = unescaped
end

初始化一个新的 MatchLastLineNode 节点。

type ()

=== (other)

源

# File lib/prism/node.rb, line 12524
def ===(other)
  other.is_a?(MatchLastLineNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (content_loc.nil? == other.content_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (unescaped === other.unescaped)
end

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