### Public Class Methods

new(source, node_id, location, flags, name) click to toggle source

Initialize a new `RequiredParameterNode` node.

    # File prism/node.rb, line 15530
    def initialize(source, node_id, location, flags, name)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @name = name
    end

type() click to toggle source

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

    # File prism/node.rb, line 15590
    def self.type
      :required_parameter_node
    end

### Public Instance Methods

===(other) click to toggle source

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

    # File prism/node.rb, line 15596
    def ===(other)
      other.is_a?(RequiredParameterNode) &&
        (flags === other.flags) &&
        (name === other.name)
    end

accept(visitor) click to toggle source

def accept: (`Visitor` visitor) -> void

    # File prism/node.rb, line 15539
    def accept(visitor)
      visitor.visit_required_parameter_node(self)
    end

child_nodes() click to toggle source

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

    # File prism/node.rb, line 15544
    def child_nodes
      []
    end

Also aliased as: deconstruct
comment_targets() click to toggle source

def `comment_targets`: () -> Array[Node | Location]

    # File prism/node.rb, line 15554
    def comment_targets
      [] #: Array[Prism::node | Location]
    end

compact_child_nodes() click to toggle source

def `compact_child_nodes`: () -> Array

    # File prism/node.rb, line 15549
    def compact_child_nodes
      []
    end

copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name) click to toggle source

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?name: Symbol) -> `RequiredParameterNode`

    # File prism/node.rb, line 15559
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name)
      RequiredParameterNode.new(source, node_id, location, flags, name)
    end

deconstruct()

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

Alias for: child_nodes

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

    # File prism/node.rb, line 15567
    def deconstruct_keys(keys)
      { node_id: node_id, location: location, name: name }
    end
