公共类方法

new(source, node_id, location, flags, numerator, denominator) 点击以切换源代码

初始化一个新的RationalNode节点。

# File prism/node.rb, line 15074
def initialize(source, node_id, location, flags, numerator, denominator)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @numerator = numerator
  @denominator = denominator
end

type() 点击以切换源代码

返回此节点类型的符号表示形式。请参阅“Node::type”。

end

公共实例方法

===(other) 点击以切换源代码

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 15163
def ===(other)
  other.is_a?(RationalNode) &&
    (flags === other.flags) &&
    (numerator === other.numerator) &&
    (denominator === other.denominator)
end
