class Prism::ConstantWriteNode

表示对常量进行写入操作。

Foo = 1
^^^^^^^

属性

name[R]

常量的名称（github.com/ruby/prism/blob/main/docs/parsing_rules.md#constants）。

Foo = :bar # name `:Foo`

XYZ = 1    # name `:XYZ`

value[R]

要写入常量的值。它可以是任何[非void表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。

FOO = :bar
      ^^^^

MyClass = Class.new
          ^^^^^^^^^

===(other) 点击切换源代码

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

# File prism/node.rb, line 5872
def ===(other)
  other.is_a?(ConstantWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end
