属性
attr_reader name: Symbol
attr_reader value: Prism::node
公共类方法
初始化一个新的 ClassVariableOrWriteNode
节点。
# File prism/node.rb, line 4216 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。参见 ‘Node::type`。

公共实例方法
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。
# File prism/node.rb, line 4314 def ===(other) other.is_a?(ClassVariableOrWriteNode) && (name === other.name) && (name_loc.nil? == other.name_loc.nil?) && (operator_loc.nil? == other.operator_loc.nil?) && (value === other.value) end

使用给定的已保存源保存 name_loc
位置,以便以后可以检索它。
# File prism/node.rb, line 4272 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,以便以后可以检索它。
# File prism/node.rb, line 4285 def save_operator_loc(repository) repository.enter(node_id, :operator_loc) end
