class Prism::AssocSplatNode

表示哈希字面量中的 splat（展开）。

{ **foo }
  ^^^^^

属性

value [R]

要展开的值，如果存在。在使用关键字剩余参数转发时将不存在。

{ **foo }
    ^^^

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

=== (other)

Source

# File lib/prism/node.rb, line 1405
def ===(other)
  other.is_a?(AssocSplatNode) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
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。

  visitor.visit_assoc_splat_node(self)
end

def accept: (Visitor visitor) -> void

def child_nodes
  [value]
end

def child_nodes: () -> Array

也别名为：deconstruct

compact_child_nodes ()

Source

# File lib/prism/node.rb, line 1337
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << value if value
  compact

  AssocSplatNode.new(source, node_id, location, flags, value, operator_loc)
end

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

deconstruct ()

def deconstruct: () -> Array

别名：child_nodes

inspect ()

Source

# File lib/prism/node.rb, line 1389
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

operator ()

Source

save_operator_loc (repository)

Source

# File lib/prism/node.rb, line 1379
