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

初始化一个新的 BlockParameterNode 节点。

# File prism/node.rb, line 1978
def initialize(source, node_id, location, flags, name, name_loc, operator_loc)
  @source = source
  @node_id = node_id
  @location = location

公共实例方法

===(other) 点击切换源代码

为节点实现大小写相等性。这实际上是 ==，但不比较位置的值。位置仅检查是否存在。

# File prism/node.rb, line 2094
def ===(other)
  other.is_a?(BlockParameterNode) &&
    (flags === other.flags) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end
