new(source, node_id, location, flags, keyword_loc, arguments) 点击切换源码

初始化一个新的 ReturnNode 节点。

# File prism/node.rb, line 16041
def initialize(source, node_id, location, flags, keyword_loc, arguments)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @keyword_loc = keyword_loc
  @arguments = arguments
end

公共实例方法

===(other) 点击切换源码

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 16123
def ===(other)
  other.is_a?(ReturnNode) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (arguments === other.arguments)
end

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 16051
def accept(visitor)
  visitor.visit_return_node(self)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?keyword_loc: Location, ?arguments: ArgumentsNode?) -> ReturnNode

# File prism/node.rb, line 16073
def copy(node_id: self.node_id, location: self.location, flags: self.flags, keyword_loc: self.keyword_loc, arguments: self.arguments)
  ReturnNode.new(source, node_id, location, flags, keyword_loc, arguments)
