Public Class Methods

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

Source

# File lib/prism/node.rb, line 15288
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 ()

Source

# File lib/prism/node.rb, line 15371
def self.type
  :rational_node
end

返回此节点类型的符号表示。参见 Node::type。

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 15377
def ===(other)
  other.is_a?(RationalNode) &&
    (flags === other.flags) &&
    (numerator === other.numerator) &&
    (denominator === other.denominator)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。

accept (visitor)

def accept(visitor)
  visitor.visit_rational_node(self)
end

def accept: (Visitor visitor) -> void

end

def child_nodes: () -> Array

也别名为： deconstruct

Source

# File lib/prism/node.rb, line 15313
def comment_targets
  [] #: Array[Prism::node | Location]
end

def comment_targets: () -> Array[Node | Location]

compact_child_nodes ()

Source

# File lib/prism/node.rb, line 15318
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? ()

Source

# File lib/prism/node.rb, line 15336
def decimal?
  flags.anybits?(IntegerBaseFlags::DECIMAL)
end

def decimal?: () -> bool

deconstruct ()

def deconstruct: () -> Array

别名： child_nodes

deconstruct_keys (keys)

Source

# File lib/prism/node.rb, line 15326
def deconstruct_keys(keys)
  { node_id: node_id, location: location, numerator: numerator, denominator: denominator }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, numerator: Integer, denominator: Integer }

hexadecimal? ()

Source

# File lib/prism/node.rb, line 15346
def hexadecimal?
  flags.anybits?(IntegerBaseFlags::HEXADECIMAL)
end

def hexadecimal?: () -> bool

numeric ()

Source

# File lib/prism/node_ext.rb, line 123
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

将节点的值作为 IntegerNode 或 FloatNode 返回。此方法已弃用，建议使用 value 或 numerator/#denominator。

octal? ()

Source

# File lib/prism/node.rb, line 15341

end

def octal?: () -> bool
