Public Class Methods

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

Source

# File lib/prism/node.rb, line 425
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 521
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 527
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.

accept (visitor)

Source

# File lib/prism/node.rb, line 436
def accept(visitor)
  visitor.visit_alias_method_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

Source

# File lib/prism/node.rb, line 441
def child_nodes
  [new_name, old_name]
end

def child_nodes: () -> Array[nil | Node]

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 451
def comment_targets
  [new_name, old_name, keyword_loc] #: Array[Prism::node | Location]
end

def comment_targets: () -> Array[Node | Location]

def compact_child_nodes
  [new_name, old_name]
end

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, new_name: self.new_name, old_name: self.old_name, keyword_loc: self.keyword_loc)

Source

# File lib/prism/node.rb, line 456
def copy(node_id: self.node_id, location: self.location, flags: self.flags, new_name: self.new_name, old_name: self.old_name, keyword_loc: self.keyword_loc)
  AliasMethodNode.new(source, node_id, location, flags, new_name, old_name, keyword_loc)
end

deconstruct ()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes

Source

# File lib/prism/node.rb, line 464
def deconstruct_keys(keys)
  { node_id: node_id, location: location, new_name: new_name, old_name: old_name, keyword_loc: keyword_loc }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, new_name: SymbolNode | InterpolatedSymbolNode, old_name: SymbolNode | InterpolatedSymbolNode | GlobalVariableReadNode | MissingNode, keyword_loc: Location }

inspect ()

Source

# File lib/prism/node.rb, line 511

keyword_loc ()

Source

# File lib/prism/node.rb, line 493
def keyword_loc
  location = @keyword_loc
  return location if location.is_a?(Location)
  @keyword_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)

save_keyword_loc (repository)

Source

# File lib/prism/node.rb, line 501
def save_keyword_loc(repository)
  repository.enter(node_id, :keyword_loc)
end

Save the keyword_loc location using the given saved source so that it can be retrieved later.
