end

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 6860
def ===(other)
  other.is_a?(GlobalVariableReadNode) &&
    (name === other.name)
end
