class Prism::CallOrWriteNode
表示在调用上使用 '||=' 运算符。
foo.bar ||= value ^^^^^^^^^^^^^^^^^
属性
表示正在调用的方法的名称。
foo.bar ||= value # read_name `:bar` ^^^
正在调用方法的对象。这可以是 ‘nil` 或任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。
foo.bar ||= value ^^^
表示正在赋值的值。
foo.bar ||= value ^^^^^
表示正在写入的方法的名称。
foo.bar ||= value # write_name `:bar=` ^^^
公共类方法
初始化一个新的 CallOrWriteNode
节点。
# File prism/node.rb, line 3053 def initialize(source, node_id, location, flags, receiver, call_operator_loc, message_loc, read_name, write_name, operator_loc, value) @source = source @node_id = node_id @location = location @flags = flags @receiver = receiver @call_operator_loc = call_operator_loc @message_loc = message_loc @read_name = read_name @write_name = write_name @operator_loc = operator_loc @value = value end
返回此节点类型的符号表示形式。请参阅 ‘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。仅检查是否存在位置。
# File prism/node.rb, line 3239 def ===(other) other.is_a?(CallOrWriteNode) && (flags === other.flags) && (receiver === other.receiver) && (call_operator_loc.nil? == other.call_operator_loc.nil?) && (message_loc.nil? == other.message_loc.nil?) && (read_name === other.read_name) && (write_name === other.write_name) && (operator_loc.nil? == other.operator_loc.nil?) && (value === other.value) end
