         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

### Public Class Methods

new (source, node_id, location, flags, left, right, operator_loc)
Source

    # File lib/prism/node.rb, line 25734
    def initialize(source, node_id, location, flags, left, right, operator_loc)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @left = left
      @right = right
      @operator_loc = operator_loc
    end

Initialize a new `RangeNode` node.

### Public Instance Methods

left → Node | nil
Source

    # File lib/prism/node.rb, line 25855
    def left
      @left
    end

The left-hand side of the range, if present. It can be either `nil` or any non-void expression.

    1...
    ^

    hello...goodbye
    ^^^^^

right → Node | nil
Source

    # File lib/prism/node.rb, line 25872
    def right
      @right
    end

The right-hand side of the range, if present. It can be either `nil` or any non-void expression.

    ..5
      ^

    1...foo
        ^^^

If neither right-hand or left-hand side was included, this will be an `ErrorRecoveryNode`.

## Flags

### Public Instance Methods

exclude_end? ()
Source

    # File lib/prism/node.rb, line 25839
    def exclude_end?
      flags.anybits?(RangeFlags::EXCLUDE_END)
    end

… operator

## Locations

### Public Instance Methods

operator_loc → Location
Source

    # File lib/prism/node.rb, line 25883
    def operator_loc
      location = @operator_loc
      return location if location.is_a?(Location)
      @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

The `Location` of the `..` or `...` operator.

## Node Interface

These methods are present on all subclasses of `Node`. Read the node interface docs for more information.
