类 Prism::CallTargetNode

表示赋值给方法调用。

foo.bar, = 1
^^^^^^^

begin
rescue => foo.bar
          ^^^^^^^
end

for foo.bar in baz do end
    ^^^^^^^

属性

name [R]

表示正在调用的方法的名称。

foo.bar = 1 # name `:foo`
^^^

receiver [R]

new (source, node_id, location, flags, receiver, call_operator_loc, name, message_loc)

源代码

# File lib/prism/node.rb, line 3266
def initialize(source, node_id, location, flags, receiver, call_operator_loc, name, message_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @receiver = receiver
  @call_operator_loc = call_operator_loc
  @name = name
  @message_loc = message_loc
end

初始化一个新的 CallTargetNode 节点。

type ()

# File lib/prism/node.rb, line 3395
def self.type
  :call_target_node
end

返回此节点类型的符号表示。请参阅 'Node::type'。

=== (other)

源代码

# File lib/prism/node.rb, line 3401
def ===(other)
  other.is_a?(CallTargetNode) &&
    (flags === other.flags) &&
    (receiver === other.receiver) &&
    (call_operator_loc.nil? == other.call_operator_loc.nil?) &&
    (name === other.name) &&
    (message_loc.nil? == other.message_loc.nil?)
end

为节点实现 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。
