class Prism::ConstantWriteNode

Parent:: Prism::Node

Represents writing to a constant.

Foo = 1
^^^^^^^

Attributes

name [R]

The name of the [constant](github.com/ruby/prism/blob/main/docs/parsing_rules.md#constants).

Foo = :bar # name `:Foo`

XYZ = 1    # name `:XYZ`

value [R]

The value to write to the constant. It can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

FOO = :bar
      ^^^^

MyClass = Class.new

new (source, node_id, location, flags, name, name_loc, value, operator_loc)

Source

# File lib/prism/node.rb, line 5758
def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc
  @value = value
  @operator_loc = operator_loc
end

Initialize a new ConstantWriteNode node.

type ()

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 5872
def ===(other)
  other.is_a?(ConstantWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_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 5770
def accept(visitor)
  visitor.visit_constant_write_node(self)
end

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 5775
def child_nodes
  [value]
end

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

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 5785

  ConstantWriteNode.new(source, node_id, location, flags, name, name_loc, value, operator_loc)
end

end

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

full_name ()

Source

# File lib/prism/node_ext.rb, line 152
def full_name

  location = @name_loc
  return location if location.is_a?(Location)
  @name_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

The location of the constant name.
