class Prism::BreakNode
表示使用 ‘break’ 关键字。
break foo ^^^^^^^^^
属性
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
初始化一个新的 BreakNode
节点。
# File 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
返回此节点类型的符号表示形式。请参阅 ‘Node::type’。
# File prism/node.rb, line 2357 def self.type :break_node end
公共实例方法
实现节点的 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 2363 def ===(other) other.is_a?(BreakNode) && (arguments === other.arguments) && (keyword_loc.nil? == other.keyword_loc.nil?) end
def accept: (Visitor
visitor) -> void
# File prism/node.rb, line 2285 def accept(visitor) visitor.visit_break_node(self) end
def child_nodes
: () -> Array[nil | Node]
# File prism/node.rb, line 2290 def child_nodes [arguments] end
def comment_targets
: () -> Array[Node | Location]
# File prism/node.rb, line 2302 def comment_targets [*arguments, keyword_loc] #: Array[Prism::node | Location] end
def compact_child_nodes
: () -> Array
# File prism/node.rb, line 2295 def compact_child_nodes compact = [] #: Array[Prism::node] compact << arguments if arguments compact end
def copy: (?node_id: Integer, ?location: Location
, ?flags: Integer, ?arguments: ArgumentsNode
?, ?keyword_loc: Location
) -> BreakNode
# File 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 deconstruct_keys
: (Array keys) -> { node_id: Integer, location: Location
, arguments: ArgumentsNode
?, keyword_loc
: Location
}
# File prism/node.rb, line 2315 def deconstruct_keys(keys) { node_id: node_id, location: location, arguments: arguments, keyword_loc: keyword_loc } end
def inspect -> String
# File prism/node.rb, line 2347 def inspect InspectVisitor.compose(self) end
def keyword: () -> String
# File prism/node.rb, line 2342 def keyword keyword_loc.slice end
’break’ 关键字的位置。
break foo ^^^^^
# File 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
使用给定的已保存源保存 keyword_loc
位置,以便以后可以检索它。
# File prism/node.rb, line 2337 def save_keyword_loc(repository) repository.enter(node_id, :keyword_loc) end
返回此节点类型的符号表示形式。请参阅 ‘Node#type’。
# File prism/node.rb, line 2352 def type :break_node end
