#left ⇒ Object (readonly)

Represents the left side of the expression. It can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

Class Method Details

.type ⇒ Object

Return a symbol representation of this node type. See ‘Node::type`.

end

Instance Method Details

#===(other) ⇒ Object

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

def ===(other)
  other.is_a?(OrNode) &&
    (left === other.left) &&
    (right === other.right) &&
    (operator_loc.nil? == other.operator_loc.nil?)
