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.

# File lib/prism/node.rb, line 5869
def ===(other)
  other.is_a?(DefNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (receiver === other.receiver) &&
    (parameters === other.parameters) &&
    (body === other.body) &&
    (locals.length == other.locals.length) &&
    locals.zip(other.locals).all? { |left, right| left === right } &&
    (def_keyword_loc.nil? == other.def_keyword_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (lparen_loc.nil? == other.lparen_loc.nil?) &&
    (rparen_loc.nil? == other.rparen_loc.nil?) &&
    (equal_loc.nil? == other.equal_loc.nil?) &&
