Public Class Methods

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

Source

# File lib/prism/node.rb, line 16992
def initialize(source, node_id, location, flags, keyword_loc, arguments)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @keyword_loc = keyword_loc
  @arguments = arguments
end

Initialize a new ReturnNode node.

Source

# File lib/prism/node.rb, line 17073
def self.type
  :return_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 17079
def ===(other)
  other.is_a?(ReturnNode) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (arguments === other.arguments)
end

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

def accept(visitor)
  visitor.visit_return_node(self)
end
