class Prism::MissingNode

表示源代码中缺失的节点，并导致语法错误。

公共类方法

源代码

# File lib/prism/node.rb, line 12812
def initialize(source, node_id, location, flags)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
end

初始化一个新的 MissingNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 12863
def self.type
  :missing_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)

源代码

# File lib/prism/node.rb, line 12869
def ===(other)
  other.is_a?(MissingNode)
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 12820
def accept(visitor)
  visitor.visit_missing_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

# File lib/prism/node.rb, line 12825
def child_nodes
  []
end

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

也别名为： deconstruct

comment_targets ()

源代码

# File lib/prism/node.rb, line 12835
def comment_targets
  [] #: Array[Prism::node | Location]
end

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

compact_child_nodes ()

源代码

# File lib/prism/node.rb, line 12830
def compact_child_nodes
  []
end

def compact_child_nodes: () -> Array

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

源代码

# File lib/prism/node.rb, line 12840
def copy(node_id: self.node_id, location: self.location, flags: self.flags)
  MissingNode.new(source, node_id, location, flags)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer) -> MissingNode

deconstruct ()

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

别名为： child_nodes

deconstruct_keys (keys)

源代码

# File lib/prism/node.rb, line 12848
def deconstruct_keys(keys)
  { node_id: node_id, location: location }
end

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

inspect ()

源代码

# File lib/prism/node.rb, line 12853
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

type ()

源代码

# File lib/prism/node.rb, line 12858
def type
  :missing_node
end

返回此节点类型的符号表示形式。请参阅 'Node#type'。
