new (source, node_id, location, flags, parent, name, delimiter_loc, name_loc)

源码

# File lib/prism/node.rb, line 5377
def initialize(source, node_id, location, flags, parent, name, delimiter_loc, name_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @parent = parent
  @name = name
  @delimiter_loc = delimiter_loc
  @name_loc = name_loc
end

初始化一个新的 ConstantPathTargetNode 节点。

type ()

源码

# File lib/prism/node.rb, line 5471
def self.type
  :constant_path_target_node
end

返回此节点类型的符号表示形式。请参阅 ‘Node::type’。

公共实例方法

=== (other)

源码

# File lib/prism/node.rb, line 5477
def ===(other)
  other.is_a?(ConstantPathTargetNode) &&
    (parent === other.parent) &&
    (name === other.name) &&
    (delimiter_loc.nil? == other.delimiter_loc.nil?) &&
    (name_loc.nil? == other.name_loc.nil?)
end

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

accept (visitor)

源码

# File lib/prism/node.rb, line 5389
def accept(visitor)
  visitor.visit_constant_path_target_node(self)
end

child ()

源码

# File lib/prism/node_ext.rb, line 243
def child
  deprecated("name", "name_loc")

  if name

  else
    MissingNode.new(source, -1, location, 0)
  end
end

以前，我们在这个类上有一个子节点，其中包含常量读取或缺失节点。为了不造成重大更改，我们继续提供该 API。
