class Prism::ClassVariableAndWriteNode
表示使用 ‘&&=` 运算符对类变量进行赋值。
@@target &&= value ^^^^^^^^^^^^^^^^^^
属性
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` ^^^^^^^^
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 ^^^^^
公共类方法
初始化一个新的 ClassVariableAndWriteNode
节点。
# File prism/node.rb, line 3978 def initialize(source, node_id, location, flags, name, name_loc, operator_loc, value) @source = source @node_id = node_id @location = location @flags = flags @name = name @name_loc = name_loc @operator_loc = operator_loc @value = value end
返回此节点类型的符号表示形式。参见 ‘Node::type`。
# File prism/node.rb, line 4082 def self.type :class_variable_and_write_node end
公共实例方法
为节点实现 case 相等性。这实际上是 ==,但不比较位置的值。位置仅检查是否存在。
# File 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

表示变量名称的位置。
@@target &&= value ^^^^^^^^
# File prism/node.rb, line 4032 def name_loc location = @name_loc return location if location.is_a?(Location) @name_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF) end
def operator: () -> String
# File prism/node.rb, line 4067 def operator operator_loc.slice end
表示 ‘&&=` 运算符的位置。

使用给定的已保存源保存 name_loc
位置,以便稍后可以检索它。
# File prism/node.rb, line 4040 def save_name_loc(repository) repository.enter(node_id, :name_loc) end
使用给定的已保存源保存 operator_loc
位置,以便稍后可以检索它。
# File prism/node.rb, line 4056 def save_operator_loc(repository) repository.enter(node_id, :operator_loc) end
返回此节点类型的符号表示形式。参见 ‘Node#type`。
