### Public Class Methods

new (source, node_id, location, flags, name, name_loc, operator_loc)
Source

    # File lib/prism/node.rb, line 17045
    def initialize(source, node_id, location, flags, name, name_loc, operator_loc)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @name = name
      @name_loc = name_loc
      @operator_loc = operator_loc
    end

Initialize a new `RestParameterNode` node.

type ()
Source

    # File lib/prism/node.rb, line 17150
    def self.type
      :rest_parameter_node
    end

Return a symbol representation of this node type. See `Node::type`.

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 17156
    def ===(other)
      other.is_a?(RestParameterNode) &&
        (flags === other.flags) &&
        (name === other.name) &&
        (name_loc.nil? == other.name_loc.nil?) &&
        (operator_loc.nil? == other.operator_loc.nil?)
    end

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