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 15435
def ===(other)
  other.is_a?(RescueModifierNode) &&
    (expression === other.expression) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (rescue_expression === other.rescue_expression)
end
