class Prism::ClassVariableAndWriteNode

表示使用 ‘&&=` 运算符为类变量赋值。

@@target &&= value
^^^^^^^^^^^^^^^^^^

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)。

@@target &&= value # name `:@@target`
^^^^^^^^

value [R]

表示被赋值的值。这可以是任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。

@@target &&= value

=== (other)

来源

# File lib/prism/node.rb, line 4088
def ===(other)
  other.is_a?(ClassVariableAndWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
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。
