          ^
    end

### Attributes

name [R]

attr_reader name: `Symbol`

### Public Class Methods

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

    # File lib/prism/node.rb, line 16672
    def initialize(source, node_id, location, flags, name)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @name = name
    end

Initialize a new `RequiredParameterNode` node.

type ()
Source

    # File lib/prism/node.rb, line 16738
    def self.type
      :required_parameter_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 16744
    def ===(other)
      other.is_a?(RequiredParameterNode) &&
        (flags === other.flags) &&
        (name === other.name)
    end

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