attr_reader maximum: `Integer`

### Public Class Methods

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

    # File lib/prism/node.rb, line 13663
    def initialize(source, node_id, location, flags, maximum)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @maximum = maximum
    end

Initialize a new `NumberedParametersNode` node.

type ()
Source

    # File lib/prism/node.rb, line 13718
    def self.type
      :numbered_parameters_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 13724
    def ===(other)
      other.is_a?(NumberedParametersNode) &&
        (maximum === other.maximum)
    end

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

accept (visitor)

    # File lib/prism/node.rb, line 13672
    def accept(visitor)
      visitor.visit_numbered_parameters_node(self)

    # File lib/prism/node.rb, line 13677
    def child_nodes
      []
    end

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

Also aliased as: deconstruct

    # File lib/prism/node.rb, line 13687
    def comment_targets

      NumberedParametersNode.new(source, node_id, location, flags, maximum)
    end

def copy: (?node_id: `Integer`, ?location: `Location`, ?flags: `Integer`, ?maximum: `Integer`) -> `NumberedParametersNode`

deconstruct ()

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

Alias for: child_nodes

    # File lib/prism/node.rb, line 13700
    def deconstruct_keys(keys)
      { node_id: node_id, location: location, maximum: maximum }
    end

def `deconstruct_keys`: (Array keys) -> { node_id: `Integer`, location: `Location`, maximum: `Integer` }
