Public Class Methods

new(source, node_id, location, flags, parent, name, delimiter_loc, name_loc) click to toggle source

Initialize a new ConstantPathTargetNode node.

# File lib/prism/node.rb, line 4526
def initialize(source, node_id, location, flags, parent, name, delimiter_loc, name_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @parent = parent
  @name = name
  @delimiter_loc = delimiter_loc
  @name_loc = name_loc
end

type() click to toggle source

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

# File lib/prism/node.rb, line 4606
def self.type
  :constant_path_target_node
end

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 4612
def ===(other)
  other.is_a?(ConstantPathTargetNode) &&
    (parent === other.parent) &&
    (name === other.name) &&
    (delimiter_loc.nil? == other.delimiter_loc.nil?) &&
    (name_loc.nil? == other.name_loc.nil?)
end

accept(visitor) click to toggle source

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 4538
def accept(visitor)
  visitor.visit_constant_path_target_node(self)
end

child() click to toggle source

Previously, we had a child node on this class that contained either a constant read or a missing node. To not cause a breaking change, we continue to supply that API.

# File lib/prism/node_ext.rb, line 243
def child
  deprecated("name", "name_loc")

  if name
    ConstantReadNode.new(source, -1, name_loc, 0, name)
  else
    MissingNode.new(source, -1, location, 0)
  end
end

child_nodes() click to toggle source

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

# File lib/prism/node.rb, line 4543
def child_nodes
  [parent]
end

Also aliased as: deconstruct

comment_targets() click to toggle source

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

# File lib/prism/node.rb, line 4555
def comment_targets
  [*parent, delimiter_loc, name_loc] #: Array[Prism::node | Location]
end

compact_child_nodes() click to toggle source

def compact_child_nodes: () -> Array

# File lib/prism/node.rb, line 4548
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << parent if parent
  compact
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, parent: self.parent, name: self.name, delimiter_loc: self.delimiter_loc, name_loc: self.name_loc) click to toggle source

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?parent: Prism::node?, ?name: Symbol?, ?delimiter_loc: Location, ?name_loc: Location) -> ConstantPathTargetNode

# File lib/prism/node.rb, line 4560
def copy(node_id: self.node_id, location: self.location, flags: self.flags, parent: self.parent, name: self.name, delimiter_loc: self.delimiter_loc, name_loc: self.name_loc)
  ConstantPathTargetNode.new(source, node_id, location, flags, parent, name, delimiter_loc, name_loc)
end

deconstruct()

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

Alias for: child_nodes

deconstruct_keys(keys) click to toggle source

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, parent: Prism::node?, name: Symbol?, delimiter_loc: Location, name_loc: Location }

# File lib/prism/node.rb, line 4568
def deconstruct_keys(keys)
  { node_id: node_id, location: location, parent: parent, name: name, delimiter_loc: delimiter_loc, name_loc: name_loc }
end

delimiter() click to toggle source

def delimiter: () -> String

# File lib/prism/node.rb, line 4591
def delimiter
  delimiter_loc.slice
end

delimiter_loc() click to toggle source

attr_reader delimiter_loc: Location

# File lib/prism/node.rb, line 4577
def delimiter_loc
  location = @delimiter_loc
  return location if location.is_a?(Location)
  @delimiter_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

full_name() click to toggle source

Returns the full name of this constant path. For example: “Foo::Bar”

# File lib/prism/node_ext.rb, line 236
def full_name
  full_name_parts.join("::")
end

full_name_parts() click to toggle source

Returns the list of parts for the full name of this constant path. For example: [:Foo, :Bar]

# File lib/prism/node_ext.rb, line 216
def full_name_parts
  parts =
    case parent
    when ConstantPathNode, ConstantReadNode
      parent.full_name_parts
    when nil
      [:""]
    else
      # e.g. self::Foo, (var)::Bar = baz
      raise ConstantPathNode::DynamicPartsInConstantPathError, "Constant target path contains dynamic parts. Cannot compute full name"
    end

  if name.nil?
    raise ConstantPathNode::MissingNodesInConstantPathError, "Constant target path contains missing nodes. Cannot compute full name"
  end

  parts.push(name)
end
