class Prism::LocalVariableReadNode

表示读取局部变量。请注意，这要求在同一作用域中已经写入了同名的局部变量，否则它将被解析为方法调用。

foo
^^^

属性

depth [R]

应该搜索以查找此局部变量源的可见作用域的数量。

foo = 1; foo # depth 0

bar = 2; tap { bar } # depth 1

深度计算的具体规则可能因 Ruby 实现的不同而有所差异，因为它们未在语言中指定。有关更多信息，请参阅 Prism 文档。

name [R]

局部变量的名称，它是一个标识符。

x      # name `:x`

_Test  # name `:_Test`

请注意，这也可以是以下划线后跟一个数字，用于默认的块参数。

_1     # name `:_1`

Public Class Methods

new (source, node_id, location, flags, name, depth)

Source

# File lib/prism/node.rb, line 12176
def initialize(source, node_id, location, flags, name, depth)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @depth = depth
end

初始化一个新的 LocalVariableReadNode 节点。

type ()

Source

# File lib/prism/node.rb, line 12249
def self.type
  :local_variable_read_node
end

返回此节点类型的符号表示。参见 Node::type。

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 12255
def ===(other)
  other.is_a?(LocalVariableReadNode) &&
    (name === other.name) &&
    (depth === other.depth)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。

accept (visitor)

Source

# File lib/prism/node.rb, line 12186
def accept(visitor)
  visitor.visit_local_variable_read_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

Source

# File lib/prism/node.rb, line 12191
def child_nodes
  []
end

def child_nodes: () -> Array

也别名为： deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 12201
def comment_targets
  [] #: Array[Prism::node | Location]
end

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

compact_child_nodes ()

Source

# File lib/prism/node.rb, line 12196
def compact_child_nodes
  []
end

def compact_child_nodes: () -> Array

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

Source

# File lib/prism/node.rb, line 12206
def copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name, depth: self.depth)
  LocalVariableReadNode.new(source, node_id, location, flags, name, depth)
end

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

deconstruct ()

def deconstruct: () -> Array

别名： child_nodes

deconstruct_keys (keys)

Source

# File lib/prism/node.rb, line 12214
def deconstruct_keys(keys)
  { node_id: node_id, location: location, name: name, depth: depth }
end

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

inspect ()

Source

# File lib/prism/node.rb, line 12239
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

type ()

Source

# File lib/prism/node.rb, line 12244
def type
  :local_variable_read_node
