# class Prism::CallTargetNode

Represents assigning to a method call.

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

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

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

### Attributes

name[R]

Represents the name of the method being called.

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

receiver[R]

The object that the method is being called on. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

### Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

    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
