Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 17832
def ===(other)
  other.is_a?(UntilNode) &&
    (flags === other.flags) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (do_keyword_loc.nil? == other.do_keyword_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (predicate === other.predicate) &&
    (statements === other.statements)
end

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