Overview

Unsigned integer wrapper

This class wraps a non-negative Integer value to indicate it was originally stored as an unsigned integer (Type 7) in Factorio’s Property Tree format.

Examples:

Creating an unsigned integer

value = UnsignedInteger.new(42)
value + 1  # => 43 (behaves like Integer)

Negative values raise an error

UnsignedInteger.new(-5)  # => ArgumentError

Constructor Details

#initialize(value) ⇒ UnsignedInteger

Create a new UnsignedInteger

Parameters:

  • value (Integer) —

    The integer value (must be non-negative)

Raises:

  • (ArgumentError) —

    If value is not an Integer

  • (ArgumentError) —

    If value is negative
