new (source, node_id, location, flags, name_loc, operator_loc, value, name, depth)

源码

# File lib/prism/node.rb, line 11683
def initialize(source, node_id, location, flags, name_loc, operator_loc, value, name, depth)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name_loc = name_loc
  @operator_loc = operator_loc
  @value = value
  @name = name
  @depth = depth
end

初始化一个新的 LocalVariableAndWriteNode 节点。

type ()

=== (other)

源码

# File lib/prism/node.rb, line 11785
def ===(other)
  other.is_a?(LocalVariableAndWriteNode) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value) &&
    (name === other.name) &&
    (depth === other.depth)
end

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