Public Class Methods

new (source, node_id, location, flags, arguments)

Source

# File lib/prism/node.rb, line 764
def initialize(source, node_id, location, flags, arguments)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @arguments = arguments
end

Initialize a new ArgumentsNode node.

# File lib/prism/node.rb, line 847
def self.type
  :arguments_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 853
def ===(other)
  other.is_a?(ArgumentsNode) &&
    (flags === other.flags) &&
    (arguments.length == other.arguments.length) &&
    arguments.zip(other.arguments).all? { |left, right| left === right }
end

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