### Public Class Methods

new (source, node_id, location, flags, new_name, old_name, keyword_loc)
Source

    # File lib/prism/node.rb, line 443
    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

Initialize a new `AliasMethodNode` node.

type ()
Source

    # File lib/prism/node.rb, line 550
    def self.type
      :alias_method_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 556
    def ===(other)
      other.is_a?(AliasMethodNode) &&
        (new_name === other.new_name) &&
        (old_name === other.old_name) &&
        (keyword_loc.nil? == other.keyword_loc.nil?)
    end

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 454
