class Prism::UndefNode
Represents the use of the undef
keyword.
undef :foo, :bar, :baz ^^^^^^^^^^^^^^^^^^^^^^
Attributes
attr_reader names: Array[SymbolNode | InterpolatedSymbolNode]
Public Class Methods
Initialize a new UndefNode
node.
# File lib/prism/node.rb, line 17148 def initialize(source, node_id, location, flags, names, keyword_loc) @source = source @node_id = node_id @location = location @flags = flags @names = names @keyword_loc = keyword_loc end
Return a symbol representation of this node type. See Node::type
.

Public Instance Methods
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
# File lib/prism/node.rb, line 17228 def ===(other) other.is_a?(UndefNode) && (names.length == other.names.length) && names.zip(other.names).all? { |left, right| left === right } && (keyword_loc.nil? == other.keyword_loc.nil?) end

Save the keyword_loc
location using the given saved source so that it can be retrieved later.
