class Prism::ConstantPathNode
表示通过 :: 运算符访问常量。
Foo::Bar ^^^^^^^^
属性
正在访问的常量的名称。在语法错误的情况下,这可能是 nil。
路径的左侧节点(如果存在)。它可以是 nil 或任何 非空表达式。当常量查找位于模块树的根部时,它将是 nil。
Foo::Bar ^^^ self::Test ^^^^ a.b::C ^^^
Public Class Methods

# File lib/prism/node.rb, line 5107 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 ConstantPathNode 节点。
Source
# File lib/prism/node.rb, line 5222 def self.type :constant_path_node end
返回此节点类型的符号表示。参见 Node::type。

Source
# File lib/prism/node.rb, line 5228 def ===(other) other.is_a?(ConstantPathNode) && (parent === other.parent) && (name === other.name) && (delimiter_loc.nil? == other.delimiter_loc.nil?) && (name_loc.nil? == other.name_loc.nil?) 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。

以前,此类有一个子节点,其中包含常量读取或缺失节点。为了不导致破坏性更改,我们继续提供该 API。
