class Prism::AssocNode

表示哈希键/值对。

{ a => b }
  ^^^^^^

属性

key[R]

关联的键。这可以是任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。

{ a: b }
  ^

{ foo => bar }
  ^^^

{ def a; end => 1 }
  ^^^^^^^^^^

value[R]

关联的值（如果存在）。这可以是任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。

{ foo => bar }
         ^^^

{ x: 1 }
     ^

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

初始化一个新的 AssocNode 节点。

# File prism/node.rb, line 1183
def initialize(source, node_id, location, flags, key, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @key = key
  @value = value
  @operator_loc = operator_loc
end

返回此节点类型的符号表示形式。请参阅 ‘Node::type`。

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 1291
def ===(other)
  other.is_a?(AssocNode) &&
    (key === other.key) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

accept(visitor) 点击以切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 1194
def accept(visitor)
  visitor.visit_assoc_node(self)
end

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

# File prism/node.rb, line 1214
def copy(node_id: self.node_id, location: self.location, flags: self.flags, key: self.key, value: self.value, operator_loc: self.operator_loc)

如果存在，则表示“=>”运算符的位置。

{ foo => bar }
      ^^

  location = @operator_loc
  case location
  when nil
    nil

    location
  else
    @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
  end
end
