new(source, node_id, location, flags, name) 点击切换源代码

初始化一个新的 ClassVariableReadNode 节点。

# File prism/node.rb, line 4329
def initialize(source, node_id, location, flags, name)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
end

type() 点击切换源代码

返回此节点类型的符号表示形式。请参阅“Node::type”。

def self.type
  :class_variable_read_node
end

公共实例方法

===(other) 点击切换源代码

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

# File prism/node.rb, line 4394
def ===(other)
  other.is_a?(ClassVariableReadNode) &&
    (name === other.name)
end

accept(visitor) 点击切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 4338
def accept(visitor)
  visitor.visit_class_variable_read_node(self)
end

child_nodes() 点击切换源代码

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

# File prism/node.rb, line 4343
def child_nodes
  []
end

也别名为：deconstruct

comment_targets() 点击切换源代码

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

# File prism/node.rb, line 4353
def comment_targets
  [] #: Array[Prism::node | Location]
end

compact_child_nodes() 点击切换源代码

def compact_child_nodes: () -> Array

# File prism/node.rb, line 4348
def compact_child_nodes
  []
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name) 点击切换源代码

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?name: Symbol) -> ClassVariableReadNode

# File prism/node.rb, line 4358
def copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name)
  ClassVariableReadNode.new(source, node_id, location, flags, name)
end

deconstruct()

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

别名为：child_nodes

def inspect -> String

# File prism/node.rb, line 4378
def inspect
  InspectVisitor.compose(self)
end

type() 点击切换源代码

返回此节点类型的符号表示形式。请参阅“Node#type”。
