class Prism::BreakNode

表示使用 ‘break` 关键字。

break foo
^^^^^^^^^

属性

arguments [R]

break 语句的参数，如果存在。这些可以是任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。

break foo
      ^^^

公共类方法

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

源代码

# File lib/prism/node.rb, line 2275
def initialize(source, node_id, location, flags, arguments, keyword_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @arguments = arguments
  @keyword_loc = keyword_loc
end

初始化一个新的 BreakNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 2357
def self.type
  :break_node
end

返回此节点类型的符号表示。请参阅 ‘Node::type`。

公共实例方法

=== (other)

源代码

# File lib/prism/node.rb, line 2363
def ===(other)
  other.is_a?(BreakNode) &&
    (arguments === other.arguments) &&
    (keyword_loc.nil? == other.keyword_loc.nil?)
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)

源代码

# File lib/prism/node.rb, line 2285
def accept(visitor)
  visitor.visit_break_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

# File lib/prism/node.rb, line 2290
def child_nodes
  [arguments]
end

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

也别名为：deconstruct

comment_targets ()

源代码

# File lib/prism/node.rb, line 2302
def comment_targets
  [*arguments, keyword_loc] #: Array[Prism::node | Location]
end

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

compact_child_nodes ()

源代码

# File lib/prism/node.rb, line 2295
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, arguments: self.arguments, keyword_loc: self.keyword_loc)

源代码

# File lib/prism/node.rb, line 2307
def copy(node_id: self.node_id, location: self.location, flags: self.flags, arguments: self.arguments, keyword_loc: self.keyword_loc)
  BreakNode.new(source, node_id, location, flags, arguments, keyword_loc)
end

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

deconstruct ()

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

别名为：child_nodes

deconstruct_keys (keys)

源代码

# File lib/prism/node.rb, line 2315
def deconstruct_keys(keys)
  { node_id: node_id, location: location, arguments: arguments, keyword_loc: keyword_loc }
end

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

inspect ()

源代码

# File lib/prism/node.rb, line 2347
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

keyword ()

源代码

# File lib/prism/node.rb, line 2342
def keyword
  keyword_loc.slice
end

def keyword: () -> String

keyword_loc ()

源代码

# File lib/prism/node.rb, line 2329
def keyword_loc
  location = @keyword_loc
  return location if location.is_a?(Location)
  @keyword_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

‘break` 关键字的位置。

break foo
^^^^^

save_keyword_loc (repository)

源代码

# File lib/prism/node.rb, line 2337
def save_keyword_loc(repository)
  repository.enter(node_id, :keyword_loc)
end

使用给定的已保存源保存 keyword_loc 位置，以便稍后检索。

type ()

源代码

# File lib/prism/node.rb, line 2352
def type
  :break_node
end
