      @flags = flags
      @body = body
      @opening_loc = opening_loc
      @closing_loc = closing_loc
    end

### Public Instance Methods

body → Node | nil
Source

    # File lib/prism/node.rb, line 24624
    def body
      @body
    end

Returns the `body` attribute.

## Flags

### Public Instance Methods

## Locations

### Public Instance Methods

closing_loc → Location
Source

    # File lib/prism/node.rb, line 24657
    def closing_loc
      location = @closing_loc
      return location if location.is_a?(Location)
      @closing_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Returns the `Location` represented by `closing_loc`.

opening_loc → Location
Source

    # File lib/prism/node.rb, line 24635
    def opening_loc
