=== (other)

Source

# File lib/prism/node.rb, line 9916
def ===(other)
  other.is_a?(InstanceVariableReadNode) &&
    (name === other.name)
end

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

accept (visitor)

# File lib/prism/node.rb, line 9860
def accept(visitor)
  visitor.visit_instance_variable_read_node(self)
end

Also aliased as: deconstruct

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes
