### Public Class Methods

new (source, node_id, location, flags, number)
Source

    # File lib/prism/node.rb, line 23582
    def initialize(source, node_id, location, flags, number)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @number = number
    end

Initialize a new `NumberedReferenceReadNode` node.

### Public Instance Methods

number → Integer
Source

    # File lib/prism/node.rb, line 23688
    def number
      @number
    end

The (1-indexed, from the left) number of the capture group. Numbered references that are too large result in this value being `0`.

    $1          # number `1`

    $5432       # number `5432`

    $4294967296 # number `0`
