Public Class Methods

new(source, node_id, location, flags, new_name, old_name, keyword_loc) click to toggle source

Initialize a new AliasGlobalVariableNode node.

# File lib/prism/node.rb, line 336
def initialize(source, node_id, location, flags, new_name, old_name, keyword_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @new_name = new_name
  @old_name = old_name
  @keyword_loc = keyword_loc
end

type() click to toggle source

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

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 lib/prism/node.rb, line 437
def ===(other)
  other.is_a?(AliasGlobalVariableNode) &&
    (new_name === other.new_name) &&
    (old_name === other.old_name) &&
    (keyword_loc.nil? == other.keyword_loc.nil?)
end
