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

来源

# File lib/prism/node.rb, line 13816
def initialize(source, node_id, location, flags, name, name_loc, value)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc
  @value = value
end

初始化一个新的 OptionalKeywordParameterNode 节点。

=== (other)

来源

# File lib/prism/node.rb, line 13900
def ===(other)
  other.is_a?(OptionalKeywordParameterNode) &&
    (flags === other.flags) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value)
end

实现节点的 case-equality。这实际上是 ==，但不比较位置的值。位置仅检查是否存在。
