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 4799
def ===(other)
  other.is_a?(ConstantReadNode) &&
    (name === other.name)
end

  visitor.visit_constant_read_node(self)
end

child_nodes() click to toggle source

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

# File lib/prism/node.rb, line 4749
