class Prism::NextNode

表示 ‘next’ 关键字的使用。

next 1
^^^^^^

属性

arguments [R]

attr_reader arguments: ArgumentsNode?

公共类方法

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

源代码

# File lib/prism/node.rb, line 13391
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 NextNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 13467
def self.type
  :next_node
end

返回此节点类型的符号表示。参见 ‘Node::type’。

公共实例方法

=== (other)

源代码

# File lib/prism/node.rb, line 13473
def ===(other)
  other.is_a?(NextNode) &&
    (arguments === other.arguments) &&
    (keyword_loc.nil? == other.keyword_loc.nil?)
end

实现节点的 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。

accept (visitor)

源代码

# File lib/prism/node.rb, line 13401
def accept(visitor)
  visitor.visit_next_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

# File lib/prism/node.rb, line 13406
def child_nodes
  [arguments]
end

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

别名为：deconstruct

comment_targets ()

源代码

# File lib/prism/node.rb, line 13418
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 13411
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 13423
def copy(node_id: self.node_id, location: self.location, flags: self.flags, arguments: self.arguments, keyword_loc: self.keyword_loc)
  NextNode.new(source, node_id, location, flags, arguments, keyword_loc)
end

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

deconstruct ()

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

别名为：child_nodes

deconstruct_keys (keys)

源代码

# File lib/prism/node.rb, line 13431
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 13457
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

keyword ()

源代码

# File lib/prism/node.rb, line 13452
def keyword
  keyword_loc.slice
end

def keyword: () -> String

keyword_loc ()

源代码

# File lib/prism/node.rb, line 13439
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)

源代码

# File lib/prism/node.rb, line 13447
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 13462
def type
  :next_node
end
