### Public Class Methods

new(source, node_id, location, flags, receiver, opening_loc, arguments, closing_loc, block) click to toggle source

Initialize a new `IndexTargetNode` node.

    # File prism/node.rb, line 9622
    def initialize(source, node_id, location, flags, receiver, opening_loc, arguments, closing_loc, block)
      @source = source
      @node_id = node_id

### 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?(IndexTargetNode) &&
        (flags === other.flags) &&
        (receiver === other.receiver) &&
        (opening_loc.nil? == other.opening_loc.nil?) &&
        (arguments === other.arguments) &&
        (closing_loc.nil? == other.closing_loc.nil?) &&
        (block === other.block)
    end
