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 9336
def ===(other)
  other.is_a?(IndexOrWriteNode) &&
    (flags === other.flags) &&
    (receiver === other.receiver) &&
    (call_operator_loc.nil? == other.call_operator_loc.nil?) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (arguments === other.arguments) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
