new (source, node_id, location, flags, numerator, denominator)

源码

# File lib/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

初始化一个新的 RationalNode 节点。

type ()

源码

# File lib/prism/node.rb, line 15157
def self.type
  :rational_node
end

返回此节点类型的符号表示。请参阅 'Node::type'。

=== (other)

源码

# File lib/prism/node.rb, line 15163
def ===(other)
  other.is_a?(RationalNode) &&
    (flags === other.flags) &&
    (numerator === other.numerator) &&
    (denominator === other.denominator)
end

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

accept (visitor)

def accept(visitor)
  visitor.visit_rational_node(self)

源码

# File lib/prism/node.rb, line 15104
def copy(node_id: self.node_id, location: self.location, flags: self.flags, numerator: self.numerator, denominator: self.denominator)
  RationalNode.new(source, node_id, location, flags, numerator, denominator)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?numerator: Integer, ?denominator: Integer) -> RationalNode

decimal? ()

numeric ()

源码

# File lib/prism/node_ext.rb, line 120
def numeric
  deprecated("value", "numerator", "denominator")

  if denominator == 1
    IntegerNode.new(source, -1, location.chop, flags, numerator)
  else
    FloatNode.new(source, -1, location.chop, 0, numerator.to_f / denominator)
  end
end

以 IntegerNode 或 FloatNode 的形式返回节点的值。此方法已弃用，推荐使用 value 或 numerator/#denominator。
