# class Prism::ClassVariableAndWriteNode

Represents the use of the `&&=` operator for assignment to a class variable.

    @@target &&= value
    ^^^^^^^^^^^^^^^^^^

### Attributes

name [R]

The name of the class variable, which is a `@@` followed by an identifier.

    @@target &&= value # name `:@@target`
    ^^^^^^^^

value [R]

Represents the value being assigned. This can be any non-void expression.

    @@target &&= value
                 ^^^^^

### Public Class Methods

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

    # File lib/prism/node.rb, line 4251
    def initialize(source, node_id, location, flags, name, name_loc, operator_loc, value)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @name = name
      @name_loc = name_loc
      @operator_loc = operator_loc
      @value = value
    end

Initialize a new `ClassVariableAndWriteNode` node.

type ()
Source

    # File lib/prism/node.rb, line 4362
    def self.type
      :class_variable_and_write_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 4368
    def ===(other)
      other.is_a?(ClassVariableAndWriteNode) &&
        (name === other.name) &&
        (name_loc.nil? == other.name_loc.nil?) &&
        (operator_loc.nil? == other.operator_loc.nil?) &&
        (value === other.value)
    end

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
