class Prism::ClassVariableWriteNode

表示对类变量的写入操作。

@@foo = 1
^^^^^^^^^

属性

name [R]

类变量的名称，它是一个 `@@` 后跟一个[标识符](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifiers)。

@@abc = 123     # name `@@abc`

@@_test = :test # name `@@_test`

value [R]

要写入类变量的值。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
        ^^^^

@@_xyz = 123
         ^^^

=== (other)

来源

# File lib/prism/node.rb, line 4593
def ===(other)
  other.is_a?(ClassVariableWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
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。
