class Prism::GlobalVariableWriteNode

表示对全局变量的写入。

$foo = 1
^^^^^^^^

属性

name [R]

全局变量的名称，其格式为 $ 后跟一个标识符。或者，它可以是符号指定的特殊全局变量之一。

$foo = :bar  # name `:$foo`

$_Test = 123 # name `:$_Test`

value [R]

要写入全局变量的值。它可以是任何非空表达式。

$foo = :bar
       ^^^^

$-xyz = 123
        ^^^

# File lib/prism/node.rb, line 8146
def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc

=== (other)

Source

# File lib/prism/node.rb, line 8260
def ===(other)
  other.is_a?(GlobalVariableWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
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。

def accept(visitor)
  visitor.visit_global_variable_write_node(self)
end

def accept: (Visitor visitor) -> void

  GlobalVariableWriteNode.new(source, node_id, location, flags, name, name_loc, value, operator_loc)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?name: Symbol, ?name_loc: Location, ?value: Prism::node, ?operator_loc: Location) -> GlobalVariableWriteNode

     ^

save_name_loc (repository)

Source

# File lib/prism/node.rb, line 8209
