class Prism::ReturnNode

表示使用 `return` 关键字。

return 1
^^^^^^^^

属性

arguments [R]

attr_reader arguments: ArgumentsNode?

公共类方法

new (source, node_id, location, flags, keyword_loc, arguments)

源码

# File lib/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

初始化一个新的 ReturnNode 节点。

type ()

源码

# File lib/prism/node.rb, line 16117
def self.type
  :return_node
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

=== (other)

源码

# File lib/prism/node.rb, line 16123
def ===(other)
  other.is_a?(ReturnNode) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (arguments === other.arguments)
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。

accept (visitor)

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

def accept: (Visitor visitor) -> void

child_nodes ()

# File lib/prism/node.rb, line 16056
def child_nodes
  [arguments]
end

def child_nodes: () -> Array[nil | Node]

也别名为: deconstruct

comment_targets ()

源码

# File lib/prism/node.rb, line 16068
def comment_targets
  [keyword_loc, *arguments] #: Array[Prism::node | Location]
end

def comment_targets: () -> Array[Node | Location]

compact_child_nodes ()

源码

# File lib/prism/node.rb, line 16061
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << arguments if arguments
  compact
end

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, keyword_loc: self.keyword_loc, arguments: self.arguments)

源码

# File lib/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)
end

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

deconstruct ()

def deconstruct: () -> Array[nil | Node]

别名为: child_nodes

deconstruct_keys (keys)

源码

# File lib/prism/node.rb, line 16081
def deconstruct_keys(keys)
  { node_id: node_id, location: location, keyword_loc: keyword_loc, arguments: arguments }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, keyword_loc: Location, arguments: ArgumentsNode? }

inspect ()

源码

# File lib/prism/node.rb, line 16107
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

keyword ()

源码

# File lib/prism/node.rb, line 16102
def keyword
  keyword_loc.slice
end

def keyword: () -> String

keyword_loc ()

源码

# File lib/prism/node.rb, line 16086
def keyword_loc
  location = @keyword_loc
  return location if location.is_a?(Location)
  @keyword_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

attr_reader keyword_loc: Location

save_keyword_loc (repository)

源码

# File lib/prism/node.rb, line 16094
def save_keyword_loc(repository)
  repository.enter(node_id, :keyword_loc)
end

使用给定的保存的源保存 keyword_loc 位置，以便稍后检索。
