### Public Class Methods

new (source, node_id, location, flags, operator_loc, expression)
Source

    # File lib/prism/node.rb, line 28686
    def initialize(source, node_id, location, flags, operator_loc, expression)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @operator_loc = operator_loc
      @expression = expression
    end

Initialize a new `SplatNode` node.

### Public Instance Methods

expression → Node | nil
Source

    # File lib/prism/node.rb, line 28812
    def expression
      @expression
    end

Returns the `expression` attribute.

## Locations

### Public Instance Methods

operator_loc → Location
Source

    # File lib/prism/node.rb, line 28791
    def operator_loc
      location = @operator_loc
      return location if location.is_a?(Location)
      @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Returns the `Location` represented by `operator_loc`.

## Node Interface

These methods are present on all subclasses of `Node`. Read the node interface docs for more information.
