class Prism::AssocSplatNode

表示哈希字面量中的 splat（展开）操作。

{ **foo }
  ^^^^^

属性

value[R]

要展开的值，如果存在。当使用关键字 rest 参数转发时，将缺失。

{ **foo }
    ^^^

公共类方法

new(source, node_id, location, flags, value, operator_loc) 点击以切换源代码

初始化一个新的 AssocSplatNode 节点。

def initialize(source, node_id, location, flags, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @value = value
  @operator_loc = operator_loc
end

公共实例方法

===(other) 点击以切换源代码

为节点实现 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。

# File prism/node.rb, line 1393
def ===(other)
  other.is_a?(AssocSplatNode) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 1315
def accept(visitor)
  visitor.visit_assoc_splat_node(self)
end

def compact_child_nodes: () -> Array

# File prism/node.rb, line 1325
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << value if value
  compact
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?value: Prism::node?, ?operator_loc: Location) -> AssocSplatNode

# File prism/node.rb, line 1337
def copy(node_id: self.node_id, location: self.location, flags: self.flags, value: self.value, operator_loc: self.operator_loc)
  AssocSplatNode.new(source, node_id, location, flags, value, operator_loc)
