Instance Attribute Details

#left ⇒ Object (readonly)

The left-hand side of the range, if present. It can be either nil or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

1...
^

hello...goodbye
^^^^^

def left
  @left
end

#right ⇒ Object (readonly)

The right-hand side of the range, if present. It can be either nil or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

..5
  ^

1...foo
    ^^^

If neither right-hand or left-hand side was included, this will be a MissingNode.

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.
