    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 `ClassVariableOrWriteNode` node.

### Public Instance Methods

name → Symbol
Source

    # File lib/prism/node.rb, line 7095
    def name
      @name
    end

Returns the `name` attribute.

value → Node
Source

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

Returns the `Location` represented by `name_loc`.

operator_loc → Location
Source

    # File lib/prism/node.rb, line 7128
    def operator_loc
      location = @operator_loc
      return location if location.is_a?(Location)
